Steam Import Saved Profil To Geforce Now

Hello at all. I just need help to import my saved profil from TSW6 which I use on my gaming pc to the geforce now account. As I started TSW6 today for the first time at geforce now it was not possible to import my saved profil. I just checked before at my pc if the game was only at dovetail live. For me it would be a nice option to play TSW at geforce now if my doughter use my pc and plays her other games. But I don‘t want to create a new profil and start at the beginning. If I logged in at geforce now my profile name is to see, but the game asked not to import a profile. Hope you can help me. I just find a offical tread the TSW is possible to use, you can see it here:
