Separate playback of left/right hand with normal selection

Hallo to everyone,

at the moment we can select one bar of any instrument and only that instrument is played. When bars of other instruments are added, these instruments will play as well.
Left/right hand should work the same in my opinion. When only the bar in the left hand is selected, only the left hand should play. Either this or maybe separate controls in the mixer (Musescore 3 had this feature?)

This is way easier than selecting every note of one hand and muting it in the properties panel or creating two separated pianos for this.
