I guess Mike put so many features in MSP even he doesn't remember them all.
I'd guess this workaround could work at least as well:
Select a song from the opened setlist (not in performance mode of course), tap/right-click/double tap or whatever you have enabled to envoke the editing function, tap the little circled arrow left in the corner and use "find and load song".
Select to view it. If it's not right simply go back and you are in the setlist again. If you want to add to the setlist ... wait there's no overflow menu for adding to the setlist as it seems. But you can still do this from the metafield edit field from there if needed. I think it's more convenient if you don't want to add it to the setlist. If the song should stay in the setlist Mike's way might be a bit more convenient. (But without leaving the setlist creation menu I don't see other ways either).
