Drum rack submixer not available in Touchable

When I create a drum rack in Live 11, I can unfold the drum rack channel in the mixer to get access to the individual drum rack channels, similar to a group channel. While touchAble lets me unfold group channels, I can not seem to unfold drum rack channels. Is this feature not implemented or am I missing something? If it is not available yet, do you plan to add it in the future?
