You might be able to do it with a search & replace on the database file - add the sub categories, then download & save a copy of the data.AcceptedLinks.txt incase you fuck it up
Then look for the one you just added & see how it's different from the rest of them - you
might be able to search for the category (let's say amateur) & then replace it with:
amateur <tab> free
If you do it in TextPad, it'll work by insering a strange character where the tab would be (it looks like a rectangle with a longer height)
Of course, do 2 or 3 1st, then upload the new copy & see how it looks before you spend all day just to find out my idea sucked
