"but I would really REALLY appreciate a way to have the new face scans added to the rosters transfer over to Franchise mode. For example.. would love to have the face scan of Konnor Griffin and Slade Caldwell in my Franchise… but I’d have to completely restart a franchise for that to be the case."
I believe they do show up in an already started franchise. Early on, they updated Pete Crow Armstrong's hair(got rid of the blue stars) and it changed in my franchise. I think all the cosmetic stuff shows, just not the updated ratings.
