Painting over automaterial

Hello, still new to UE.
Is there a way to paint over the material after applying an automaterial ?
If so, how ?
Thanks !

Anybody out there ?
Every single video tutorial I found had the old modes on the side, which seems very functional. But for whatever reason, that’s gone in 4.25 and I have no idea how to paint now. Any clues on how to use this new system ?
