It can be quite a lot to have to build at multiple stations for a single item to then have to wait for them all to finish, grab them, and then bring them to the station you're crafting at. I think it'd be beneficial to be able to use materials that've finsihed crafting at the stations without having to grab them or be able to queue all the necessary items at the station you're currently crafting your item and then be able to use those crafted materials for that item.
