This is indeed a much needed feature, in fact the one I'm missing by far the most in my daily professional work. I work in a studio with two control rooms where my production partner and I both work in Studio One but use entirely different I/O environments in our rooms. Setting up new Ins and Outs every time we swap a project file is a total headache. For instance, if my partner records a sketch and we want to take it to my room to finish and mix it through all the hardware I have this already consumes a lot of time setting up all the Ins and Outs of my EQs, compressors, summing mixer etc.. It's just massively frustrating that a DAW as fantastic as Studio One lacks this ultra-basic feature.
