Add an easy way to see the shop to which a vendor is assigned

[Guitarmike47]

Right now, I can assign a vendor to a shop from the staff management screen. Once I've done that, however, there is no way to see where everyone is assigned on that page. It would be great if a column could be added showing which shop each person is assigned to. It's a hassle to have to open the info panel for each shop individually or for each vendor.
