More automation questions!

First off, yes I'm in X1b.

Say I have an automation envelope on one parameter, and it's really complex, and would be a pain to do all over again for a different envelope on the same track, controlling a different parameter. Is there a way to duplicate the first envelope and be able to select between the two on one track?

Also, I've been having problems copy/pasting a clip to a different track with all automation envelopes into another track. Yes, I do Copy, everything is properly checked in the dialog box, and even do "Paste Special" ..... But it doesn't work sometimes. A lot of the time. I'll get maybe the Pan envelope copied or something, but not all envelopes. Is that a bug or is there something I'm missing?
