Click the gig book in the main library [Songs]>bring up the overlay [there will be a selection bar with icons across the top and bottom]>click the circle with triangle at the bottom left>select the snippet tool. You enter the page name/number[s] of the song you want. This will create an entry in the main library that can be treated like a single song.
There's another way to get the snippet tool also, but I don't remember how right now.

Found it. You can setup a spot on the screen to respond to a touch action; settings> touc & pedal settings>touch actions.

Edit; Separate the page numbers using a comma, 12, 13, 14, 15 , etc.
