Offline Roster update problem

hi community, i gotta game bought it on release day but i'm kinda disappointed i can't manually update roster like download them from internet and put them into game, i'm writing this here now because i got my router damaged and i'm gonna wait for like 2-3 weeks for replacement, can you help me to get this working somehow while i'm offline i can't believe this game is so limited that you can't even put rosters for offline use, i mean game is great and gameplay is great but this should be normal not to ask how to do it on forums for such a simple thing lol, anyways any help is greatly appreciated

No method for this is currently known, but there's a good chunk of people working on it, so hopefully soon enough.
