It would be nice to get an item from the Master Writ merchant that, if you have all four of a set, allows you to make them into one station. Probably something you use, click on one of the items for the set you want to combine and get a confirmation dialog that tells you you're about to combine a, b, c, and d stations. I'd imagine the station itself would be 2-3 times the length and about the same depth as the normal stations. To simplify things it could only create and improve pieces as adding the other features would clutter the menus a lot.
Such an item would really help people who have all the crafting stations in their houses and still want them to look nice. Especially with the ever increasing number of craftable sets.So I hope it will be considered.
