Courtesy Notes For Trills

I'm looking to contribute to MuseScore as a way to give back to the community.

One idea for a contribution that I had to this project would be to implement an easy-to-use non-standard trill. Oftentimes in music notation, you want a trill to go between two notes that aren't a half-step or whole-step between each other. In this case, I've often seen a small note in parentheses to indicate the 2nd note of the trill. I know there's a way to imitate the courtesy notes here:

But I think it would be useful to have a more user-friendly way to do it, and to perhaps have that trill reflected in the midi playback.

If this is a reasonable and useful contribution, let me know. Otherwise, perhaps you all have some ideas for a different contribution.

Edit: I also don't know if this is the right forum to post this, if there's a better place to ask, let me know.
