Question: is it possible to create (using the action button maybe) a 'select 2 out of X' input switch for the image compare from RGthree?

[stephantual]

A picture paints a thousand words:

I'm doing this demo tutorial on how to use SDXL 'properly'. In order to demo the outcome, I generate 3+ outputs with various techniques. So far so good. Now i want to compare the results. So i use the excellent Rgthree 'image compare' but.. it only takes TWO inputs (evidently).

Let's imagine I have three outcomes refered to as A, B and C.
How would I organize my workflow using RGthree to be able to quickly select "A vs C" or "B vs C" or "A vs B" (you get the point).

The image i uploaded is simplified on purpose, the 'real' output has dozens of potential outputs, hence why i think Rghtree woudl be useful here, but I can't wrap my head around a 'clean' way to do this.

Any pointers, worflow examples etc would be appreciated. Thank you!
