I can assign Numpad "1" to toggle several other things simultaneously via Key Mappings. Why cant I assign it to control two different Macro Variation buttons?

Oddly enough, Im able to multi-keymap the up/down arrows and the "master" play/bang button on Macro Controls located on different tracks with a single key mapping (the Key Mapping buttons at the top of the Macro Variation area).
The only part of the Macro Variations that seem to require unique Key Mappings are the individual play/bang buttons for individual Macro Variation states. Of course, these are the ones I want to utilize.
Ive raised this to support as well but Im hoping someone here has a solution. Ive not used Macro Variations much until just now so I may be missing something obvious.
