Actually, I have to do the exact same thing for the more promising large-scale builds that I've been whittling on. But I don't exactly see how this might be cleanly done; it seems like you'd have to probably specify the power system's architecture during case creation, and then going back to make corrections after the fact, which may or may not work out neatly, depending on what went into the module spec.

But also, sometimes when cobbling together the amperage-check racks, I'll notice something that maybe could've been handled better. So I'm not at all averse to that method of checking current loading. To me, it's just another aspect of the refinement processes of a given build.
