End point manager same file for diferents brands

I have created two templates: 922 and 962. They are based on spa922 and spa962 respectively.

The problem is that when I change the mac.cfg or global.cfg of one template the other file is changed too.

There are some options that I want in one templante and I don’t want in the other like lenguages.

How can I create different files for each model of phone?
