More Layers in Drum Machine Pads

Is it possible to add more layers onto each pad in the drum machine?

If not, it would be great to see this going forward - with this new instrument track type it’s incredibly simple to sample and build entire kits with simple level controls (macros) for overhead or room mics. Recording a live kit and turning it into a super detailed writing or production tool now takes only an hour or two, but the limitation is multi-mic’d sources when you have bleed, overheard, rooms, etc - they just don’t fit into the 4 layers.
