Exporting Custom Re-Brands

Hey all. Not even sure who is here anymore but a quick question I had about exporting re-brands from MyLeague. I know that there has been a method to export the MyLeague in it's entirety, but when I have messed around with that, none of the other teams become available. Essentially, it is whatever teams you have in MyLeague, so a max of 36. No historical teams. No euro teams.

Ideally I would love to export just my rebrand, and re-apply them to team files in the file explorer. Just wondering if anybody knows how to export data like that.
