I have a mod that utilizes multiple master files (GOTY files) and calls itself a master file. What I wanted to do is move an item from it into another mod that I'm working on but GECK won't load it due to 'multiple master files' selected or something close to that. Is there a way around this?

For the record I made sure it showed patched correctly since installing it with steam was a trick initially

In your 'GECKCustom.ini' file, do you have this set?
bAllowMultipleMasterLoads=1
