I updated the "Brand" field on the set information page to "TCM". By defeault that field is filled with the set title. It has to be edited if the brand is not the same as the set title. It is not often done, but as a "set guy" it is important to me. It's a little tricky to navigate to that page and I'm not sure at what permission level it is accessible. I think it might be level 8.
edit: to get there (at least this is how I get there) Go to the year of the set you want to edit. All the sets for that year are listed and at the end of the set name is "(edit)". Clicking "edit" gets you to the set information. That's where the "brand" field is located. Again, I think you need to be level 8 to edit those fields.
My two-cents is worth slightly more than a penny.
