Emu XL-7 & MP-7 User's Group

hello to all group users... (no pun intended)
Just a quick question about preset edit in my MP-7. I'm trying to 
make a layered kick &  bass combo out of the same instrument. Is 
there a way to layer a single kick over the keypads. So my bass will 
have the same kick layered over the entire keys. Just let me know if 
ther is a way to make this happen...
peace,
