RFC to change entered eight notes in one time with 'Beam properties' eight notes

Hi,
Please see the attachments.
Attachment 1: Original file to convert to MuseScore.
In this file, many eight notes are present.

Now, when input this file in MuseScore (using the keyboard for enterting notes), all eight notes are entered 'together' (see the result in attachment 2 - Draft file.

I want to convert all these eight notes to seperate eight notes, using the 'Beam properties'. But now, it's not possible to select 1 or 2 measures, and drag and drop the eight note from the 'beam properties' to the score, and convert all selected eight notes in one time to the ones i want.

#
#Update: i discovered, double click on the eight note in 'Beam properties' is working...
#

Is there a possibility for this, or not at this moment?

If not, is it possible to implement this?

i hope everything is clear in my Dutch English ;-)

Thanks

Theo
