Thank you, Dietz.
I might be misinterpreting your little YT video but what you show is two have 2 different arrangements (ABCD and DCBA) for 1 identical venue, correct? You kept the venue and only switched the main mic.
What I would like to achieve is to have 1 identical arrangement (ABCD) for 2 venues. Applying that to your scenario in the YT video: arrangement ABCD in venue "Grosser Saal" and in a second MIR venue tab having arrangement ABCD in venue "Mozartsaal"
In reality I have more instruments than only two violins but I used that example to keep it simple in describing the scenario. If I were to duplicate all channels, then that would be something that I want to avoid. I would also prefer to keep the DAW out of this as I feel it should be a thing only between VEP and MIR.
But maybe I have not fully understood your proposal.
