Batch processing

Hi, gang!!!

I wonder if there is a way, inside or outside, MuseScore to perform a "Batch Processing" (something like we can do with audio files) and to change the instruments we are using in a lot of MuseScore files.

For example: Think about we have created 30 scores to a male quartet (it's my case), and we used (just as a sample):
1) Trumpet to first and second tenors,
2) Trombone to baritone, and
3) Tuba to bass.

Then, because something about the sound, we want to change the instruments of all those scores, let's say:
1) Violin to first and second tenors,
2) Cello to baritone, and
3) Double Bass to bass.

How can we perform that change without to have to use the main MuseScore program and to open and to save each file individually?

Or... Why not to use the main MuseScore program to perform this, directly? ???

Maybe I missed something and it is possible, today...

Can we? How? ???

If there isn't any way to make it...

Can the program development team to include this capability in a future version, please? ???
