why assign separately for mixture and condition if can be binding to both? same with chopper fixwing trims… we can find some models where some mapped axis will use for other things and there we can use this diversity of axes. so developers will have more room to fold wings or open canopy or whatever… but as option mixed “x/y” logic would be cool, because those mixed option can be used too by developers as another one. but first of all this is convenient for lazy people:)
