Conversion between triplet and 8th notes (to solve: deleting triplets without deleting notes)

I've noticed that you can't remove a triplet without removing its notes in it (https://musescore.org/en/node/311439).

This is very annoying in swing music where 8th notes are played like triplets and their notation gets often exchanged.
Another situation where this a problem: a song with a melody played in triplets and chords played in quarter notes (see Interplay by Bill Evans). If you play this in a DAW and import the notes with xml into Musescore, the chords initially appear as parts of triplets and to be able to separate them in a separate voice or staff you have to manually reenter every note, which is very time consuming.

Suggested solution (feature request):
A function to convert a triplet to two 8th notes by using the notes of the 1st and 3d time of the triplet and viceversa.

Examples:
ta ki da, ta ki da (2 triplets) >> ta da, ta da (4 8th notes)
ta da, ta da (4 8th notes) >> ta silence da, ta silence da (2 triplets with silence in the middle)

Ideally this function would also convert:
ta silence silence, ta silence silence (2 triplets) >> ta, ta (2 quarter notes)

Let me know what you think about it!
