[LAU] Ardour: Taking out bits of a song

Hello all, I have a project in Ardour which has much more iterations of verses than the fnal project wil have, for the sake of explorations, improvisations, etc. Is it practical to work on the structure itself or should I redo all the tracks from scratch with a new count of verses ? By 'practical' I mean are there tools and tricks that would make it easier to take out one verse made out of say, 7 tracks ? The project is in sync with the metronome, if it helps. I can see that it is possible to select one verse across all the tracks and then delete it. Since I do not know that much all that Ardour can do, I'm asking here if there are better ways to do that using specific Ardour commands that might be better to the task than selecting with a mouse on a finer-grained display of the tracks. Is it also possible to store a cut-out verse somewhere persistently to use it later ? - thanks for any comments and suggestions ! Cheers.
