Right now when one adds a profile via the UPC# method there is no way to know that you already have the UPC is your local database until you click on the "Add to" button do you get an Error Pop-up stating that "Insert Title Name" is already part of your "whatever".

Seems clear the program already knows that the UPC# is in your local database.

So I would like to have it known to the user that a UPC# is in ones local database without having to click on the Add button.

Perhaps have a new window section below the title come up stating that it's in your local database and where. Or have the same icon that appears in the Add by Title Window for the Status come up to the Left of the Title.
So if it's in ones Owned section a little 'House' Icon would be seen right by the title  below the UPC# entry.

(In other words carry over the Status Icons over to the UPC# Entry Window)

Hope that makes sense.
