Oh, so it is as simple as I was hoping.
That was the issue I was running into, though. I could turn it into a soft clothing to just allow tails and ears, but that's a material change. A further idea was just being okay with it allowing everything, but making it a very costly recipe.
Going that route, I guess I should probably add a recipe book as well. High electronics and... Fabrication, I'd assume?
While I'm at it, I might as well add in a part for another pet-peeve of mine and put together some kind of future holster and scabbard that works for the power armors. Time to go look at the Hauling Frame to see how that is allowed to attach.
Thanks for the help, Coolthulhu!
