Halo Reach File Share Limit/No Slots Remaining

With the recent announcement that Legacy titles will be able to transfer forge/custom maps I started uploading to the file share but I hit a limit and was told to subscribe to Bungie Pro to obtain more. Does anyone know a way I can upload more of my custom maps so I can have them on MCC? How do I obtain more File Share slots?

Can’t you just upload six at a time multiple times, deleting ones from your fileshare as needed after migrating them, then replacing them with 6 different ones?
