(Not quite) Resampling on OP-Z

I’m running up against drum track limitations and so I need to combine my drum and snare tracks to free one up for more samples.

Is there an easy way to access the stock drum hits and recompose them as a new kit?

Idea that is roughly like resampling:

Make a new pattern using those sounds but just put each sound you want on a step making sure that different tracks don’t clash, record out to a computer. Then bring it back into the OP-Z.

Any better suggestions?
