Ability to convert existing material into tuplets

Your idea

Would like to be able to select a passage of existing notation and convert it into a tuplet, preserving all the original notation, but now under a tuplet bracket/number, and using up the expected note durations.
Would like to be able to take an existing tuplet and remove the bracket/number to indicate the original note values etc. (possibly also changing to a different ratio tuplet)

Problem to be solved

I come across situations requiring this quite frequently.

It would obviously typically cause the total duration to reduce, much like changing a half note to a quarter note, so extra rests might be required.
Conversely, removing the tuplet indicator/bracket to revert to "plain" note values would cause total duration to increase in most cases, so it would act the same as converting a quarter note to a half note, erasing existing notation as necessary.

See my comment below for one way this could work that would mean sacrificing the current behaviour when using ctrl+ on range selections.

Prior art

Encore supported this, and at least one other engraving package I've used.

No files, tests, or entry points are named. Start by tracing how range selections and Ctrl+number currently create tuplets, then define behavior for converting plain notation to tuplets and removing or changing tuplet ratios; done means notation and durations are handled consistently in both directions.
