Flatten multiple patterns?

Is there a way to flatten multiple patterns down to one pattern in one go? I typically make one pattern for just one or two pads at a time so that if something doesn't sound good, I can just hit "clear" from inside of the pads view. The problem is that I wind up with a lot of patterns that just have one or two hits on them period. I'd like to flatten these down. It would even be cool if there was a way to create a new pattern from the beat currently programmed into a given pad cell so that you could do the opposite if you had a really good rhythm going on just one or two pads on a more complex pattern.
