Using Mainstage to set a pedal board (a Boss GT-1000) to set it up for the next song in the set

Before I buy Mainstage and invest time in the learning curve of the product can someone verify that it's straightforward to do what I want to do with the app?

I'd like to set up a series of patches in mainstage to put my pedalboard (a Boss GT-1000) into the right settings for each song. Then I'd like to program a control on the pedalboard (or it could be a new MIDI controller alternatively) to send a MIDI command to Mainstage as a trigger to have it advance to the next patch (the patch for the next song in the set list). That way, when playing live, I simply hit the control at the end of the song and the GT-1000 is set up for the next song in the set list. Yes, I could do the same by moving around the patches in the GT-1000 to be sequential and then just move up a patch but 1) our set list evolves and 2) I reuse some patches between songs (and would rather not create multiple copies of the same patch as that takes up space and also would require keeping the multiple copies of the same patch aligned as they evolve over time).

I'm pretty sure this would be straightforward to do with Mainstage. It's just an incoming MIDI command tied to advancing the patch and then outgoing commands to tell the pedalboard a pedalboard patch number to go to (and, for extra credit, enable some options for that patch like for example turn on an effect like delay or chorus as that would permit more reuse of standard patches in the pedalboard).

I am not asking for instructions on how to specifically do this necessarily (any guidance would be appreciated however)... I am looking mainly for confirmation that what I am proposing is practical with Mainstage. I was thinking to code a little Mac app to do this myself (calling the MacOS MIDI class) before I found out about Mainstage.
