Customizing enumerations/master template

Hi all

Basically a year ago, we had the need to customize 1 enumeration in all project areas. All of the other enumerations remain the same in all project areas.

Prior to this, all of our enumerations were pulled from a Master process template that all of the areas use, so we could make edits in only one place.


It seems as though if you customize 1 enumeration, you have to customize all...
Just wondering if i am mistaken and there is a way to only edit one of these, while the rest are pulled from the shared Master template we are using?

Thanks for any help!
