Hi All!

I've got an interesting question for ya.  We have a number of Custom Properties defined for Part and Assemblies, two of which are the "Vendor Part Number" and "Internal Part Number."  In our drawing, the title block automatically links to the "Internal Part Number" which has been mostly fine except when we run into funky off-the-wall cases.

I'm wondering if it's possible to put a drop down menu into the Custom Properties of the Drawings that would switch between "Internal" and "Vendor" part numbers.  This selection would then in-turn update the linked custom property in the title block to the appropriate property.  Is this something that's possible, or would it be more realistic to have two separate sheet formats?

Thanks!
