combining tracks?

never heard anyone speak of this but is it possible to combine several tracks together into one track? im interested in bangin out my drums all on seperate tracks then combining them together into one after im done. each seperate drum takes up lots of tracks when i get really into my drums.

sorry if this question was answered before. but i was really curious. i use the mpc 2000

thanks to anyone who responds.

Yea in the Edit (Events) page... change mode from replace to merge
