edit preprogrammed drum pattern/program?

[Alp]

I like some of the drum programs available on the M50, but sometimes I want to edit them, to remove a cymbal crash or such...

Currently I need a shuffle program but the closest I can find is P115 but it has too much , I need to simplify.
Not educated enough yet to build my own...

Is there a way to copy this program, edit out the stuff I do not want and save it as a (user) usable program??
