2 Midi Controllers with Concert

I've created a concert in Mainstage 3 with multiple patches for use on live gigs. When I setup this concert I had just 1 controller (Arturia Keylab 88). I have a MacBook Pro used for the live performances and a Mac Pro trashcan in my home studio used for rehearsal and concert updates etc. I keep the concert in a Dropbox which enables both Macs to access the file. When the concert is updated on either Mac it the concert stays current.

I recently purchased a Nektar Impact LX49 controller for use in the home studio for practice with the idea of adding it to my live rig in the future.

The Nektar has been added to the Concert Layout page as the second keyboard. Ideally I would like to be able to open this concert on either Mac using either controller and be able to access to play, edit or update all patches. Can this be easily done?

Thanks for the advice.
