Yes, you can drag-copy the pattern-block, just as you do with normal note-blocks.
(geshh... think.. you can.. mmm not 100% sure 1.1.3 has this.. yet. I have messed around wit crashing PRs for really long, but i promise the l o n g waiting is worth it, ...when the crash-bugs are crushed ://
At least try it..
As long as you keep it inside the same track, it is ok. It is a little tricky if you copy to a different track. The block will not be controlling the new track, but still point to the former! You need to rebind the dial you like to automate
If it fails, there is still my old proggy.. I know that can
