Seeking to Create an Arpeggio from ALL Tones Present [That Are Split into Two Voices] on the Same Staff

To Whom It May Concern:

I have MuseScore 3.5 on my computer. The specific specs are copied below for troubleshooting purposes.

OS: Windows 10 (10.0), Arch.: x86_64, MuseScore version (64-bit): 3.5.0.13199, revision: 43c5553

I am writing a piano reduction of a piece of music accompaniment for use to play live with a vocalist. I have recopied a selection from the middle of the given piece in a fresh sample for the sake of this inquiry. The MuseScore score template is [Voice + Piano]. In the right hand (RH)/Treble Clef of the Piano Grand Staff, I have highlighted three notes on Beat 3 of Measure 1 in the Excerpt that have varying duration lengths, yet they all start on the same beat. I am interested in seeing if MuseScore 3.5 can do two things which I am already physically able to do as a pianist with my two playing hands and regular notation paper and pencil, yet I seem to be bumping up against some barriers in creating the same effect using the MuseScore 3.5 program.

I want the aforementioned three notes to play together (as if they were one voice), but using the same added arpeggio for all 3 notes. The chord at Meas. 1, Beat 3 is a G+add9 (or aka B+7/G to musicians who like to separate the actual chord that is being played in the RH from the true chord's root which is being played in the LH/bass clef) and I am looking to begin a 9-8 suspension with a single upwards arpeggio being applied to ALL three highlighted notes of the RH by resolving the G+add9 chord down to a simpler G+ chord in passing heading into Meas. 2.

I created a fresh visual Excerpt (with omitted words) and am attempting to verbally type out the scenario in concise musical lingo, trying to help walk you through my concerns so that you are able to understand my inquiry properly. I hope I am doing well.

On Beat 3, the root of the G+add9 chord (G) is played on Beat 1 of the measure (and repeated in unisons in other syncopated parts of the measure) in the Piano Bass Clef. The other three ascending voices of the chord (B, D#, and A) are found in the RH/Treble Clef and are meant to be played together on an upward arpeggio on Beat 3. The two lowest notes of the RH (B and D#) are being held out on a half note while the upper voice (A) is highlighting the lyric melody on a dotted rhythm [a dotted quarter note on (A) leading down to an eighth note on (G)] which creates a [G+add9 - G+] chord progression and the 9-8 suspension in the chord resolution.

Because the three notes on Beat 3 of the Piano RH/Treble Clef have differing beat values, even though they are physically being played together by the same hand (the RH), MuseScore 3 forces me to write the B and D# (half notes) in one voice while I must write the A (dotted quarter note) [and subsequent descending eighth note on (G)] in another voice. Thus, when I attempt to create a single upwards arpeggio affecting all three notes together, the program is creating two separate arpeggios for the three notes (because they are in two voices), and this issue does NOT create the desired visual or aural synthesized affect I am looking for in the RH of the piano reduction. I am trying to create a single upward arpeggio for both voices (including all 3 notes) of the RH together (as if they were one voice).

Is the MuseScore 3.5 program formatted in such a way to allow special methods for the creation such an upward arpeggio that affects all three notes of the RH together as if they were written in ONE voice, both on the notation template and including the sake of playback?

Sincerely,
Everett Baranowski
