It's not the profiles themselves, it's the GPU names in each rig. At the moment under GPU tab all we can see is the manufacturer (at best - some of my cards don't display even that) and not the model. So in my case I have mixed GPU models in each rig and it's pain in the ass to sort out which card is where, especially when you add/change something and have to reassign profiles to each card as their numeration had changed.
