Visio ERD - how to modify Owner

Anybody use Visio to draw ERDs? I was given this VSD with an ERD within, and am trying to include a new table. When I look at the Database Properties, the Physical Name and Conceptual Name can be edited, but the Owner field is not editable at all. Whether it's a new entity table or a copied-and-pasted entity.

How can the Owner field be modified?

I think it is only available or rather shown when the drawing is linked to a database. Only using databases like SQL Server will display the owner field.

Wow, that is what i call bueraucracy.

I think Oracle (or maybe even MySQL) with specified owners and schemas will probably show the owner fields too. (At least I hope they do since Microsoft is on to interoperability now.)
