Swap between Old and New Musescore Instrument Sounds

I really like the new Mixer and Instrument Sounds in Musescore 4, but I find myself switching back and forth between the old and new sounds for large instrument groups frequently to compare how a score sounds in playback. Being able to switch the sounds of the entire score all at once instead of one instrument at a time would be a nice inclusion in a later update. (If this can already be done in the current version of Musescore 4 please let me know how to do this)
