I've got a mantis - when I need to check this I just take 3 copies of the full rack and remove all but the relevant modules for each zone, check etc and then delete after i've plugged stuff in - my mantis doesn't change that much though I mostly use it for video synthesis and I have plenty of other cases (some of which I have to do the same for!)

Utility modules are the dull polish that makes the shiny modules actually shine!!!
