Adding created player to MyGM Mode! Possible?

Hey guys.
I tried a lot, but haven't found a way to add my created player to the GM Mode (or MyLeague).
Is this even possible? If yes, how?

Thanks alot

I don’t play MyGM but this should be easily doable. Can’t you play MyGM with custom rosters this year out of the box?

sadly it' not possible to start MyGM with a custom roster or sorts (I guess - haven't found a way yet).
