While the "expanision of duties" scroll in Housing allows players to use Retainers as housing furnishings (1, 2 or 3 based on your size of house), I feel like I'd like a more "free" use of the retainers in either/both Squadron Room or Housing.

I bought and use Max allowed Retainers at a very expensive monthly fee to "hold items" and sell items. A more visual presentation rather than summoning them individual or max with scroll isn't ideal to me. This is especially fun with glamours.
