Parameter slide between patterns?

Is this possible?

I find myself tweaking a pattern until it sounds good, then copying it and pasting it so I can tweak it again into something new.

When I play back the two patterns in a chain, it sounds great but the change can be abrupt. I’m wondering if I can parameter slide between the patterns to smooth it out a bit?

Any other helpful workflow ideas for managing this would be welcome too (always good to learn how people are working on stuff)
