Custom UI Editor to Modify Ribbon Word 2007

Hello,

I recently modified my Word 2007 Ribbon using the Custom UI Editor and
it was very straight forward. I have a template (.dotm) in the Word
startup folder that contains some VBA which is attached to a custom
icon on a new Tab /Group on the Ribbon.

Probably very simple, but my question... how do I associate a 2nd
template in my startup to this new Tab? preferably in a separate
group?

Thanks for any help!!
