Had an idea that I think would make crafting multiple items together much easier

Say for example you want to craft a whole set of gear for a class, that's 13 items of materials, getting it all from a retainer is a pain. My idea is a list where you go through the crafting log, add to craft list and once your done, it tells you a total of materials you need (13 Hippo leather, 18 twin thread, 24 cashmere cloth, 20 wind clusters, 20 earth clusters) etc. and also put a quantity part for making cashmere cloth for example. Shouldn't be toooo hard to put this in
