adding one montage to another montage

I created two separate Montages for a live orchestral recording I did: Set1 and Set2. It now turns out that, after some editing, the entire concert will fit on one CD. So, what I would like to do is add the set2 Montage onto the set1 Montage. Is there a way to do this?
Thank you.

The only and easiest way I know is to Select All (ctrl-A) the clips in Montage 2, and copy and paste them at the end of Montage 1, then save Montage 1 with a new name if needed.

Make sure the markers in Montage 2 are bound to their clips first, and Full Clip Attachment is selected on the Markers tab Functions menu, so that the markers will go over in the paste. (those might be in place already so I would just try the copy/paste and see if it works as expected).
