Ability to change note variants from Edit Drumset window

When creating/editing the palette for unpitched percussion instruments, I would like the ability to change note variants from within the Edit Drumset window.

Currently, this is only possible through editing the .drm file or .xml file and adding along with whatever variants you want to add. You can change the MIDI pitch by adding articulations or tremolos to a note. MDL does this where you can use the buzzroll tremolo to change a "Hit" sound to a "Buzz" sound and with other various techniques.

In the Edit Drumset window, however, this cannot be changed and you are only able to see the notes that would appear in the palette. The pitches that the variants should be found at appear empty in this window.

Here is an example using my mapping of a VDL instrument:
