Measure numbers below a system without need of manipulating them

I learned that I'll only get measure numbers below a system if I activate those numbers for all staves and then disable visibility for the redundant numbers. This sounds quite odd to me - needing to manually and individually disabling way more than 100 numbers within a small song with voice & piano.

So, I'll request the new feature that bar numbers which aren't set for every stave but switched to below would automatically be set to below the last stave in the system (Y being calculated from the last staff in the system) - with no change in the GUI! This would be a great deal for me and probably a lot of other writers for big band music. What if I wanted to write a direction sheet and then extract the single parts? That would result in disabling and enabling measure numbers all the time, wouldn't it?

I know MuseScore is a work of volunteers, but this change should really be worth the effort!
