@Ian-Schwartz If you right click at the top of your Movies the're options, as far as i know you can only merge two movies into one each time, so you may have to merge 1+2, 1/2+3. 1/2/3+4..
If you were using Vegas Pro your individual movies would be nested timelines that auto update the main Parent timeline, which you can then just export that one main timeline (or each nested timeline) but as I say I don't know if that's poss with MMS.

This is not possible with MMS however it is possible in Video Pro X which, if this feature is essential, would be the choice of program to upgrade to - the work flow is the same and existing MMS projects could still be opened and edited.
