Modifying globals

I recently started playing 2k14 again and after downloading a global I've noticed that most of it is great, but some aspects are better in other globals. Is there a way to open the global file to edit it and add in files from another global?

I'm thinking most specifically of accessory/sock mods.

could anyone remove nba logo from this global made by seanjohn22 and edited by dee4three:
