It seems a bit involved. Can it be streamlined to where a user just:
1.Selects '+ New' at the top.
2. Selects the source file, enter the new name of the assembled new song/medley, the page numbers/order to be used, all on one popup.
3. Presses ok.
4. Taken to the editing page to complete the editing, the 'title' being the one in step 2..  

I would help, if streamlining is not feasible/not desired, to include a more detailed description of the operation in the help manual.

I was mulling over a similar suggestion, but starting from within the (multi-)song, so you can view the new page(s) and create/copy the new song directly from the respective page (and preferably go direct to the edit of the name field, also suggesting the viewed page in the page number/order field).
