I think that you should be able to move things from your inventory to your shop/wardrobe more than one at a time. That way you can move a whole or part of a stack all at once.

There is quickstock. It's under the 'Your Shops' menu

I did not know that, thank you!

No problem :)

It took me about a week to find it!

Ok, now i don't feel as bad about it.

Locking this, as it's already a feature :)
