Yeah, as I mentioned, this I could do, but I already have all the material instances on my objects and named. If I reload my assets via datasmith, the names should be the same, so I can reapply them easily.
For example. I have 20 Treeshaders, and I finetune one of them. Now I have to delete, duplicate and reapply every shader, every time I change something. There hast to be an easier way I hope.
Especially in interior design, you have this situation multiple times a day. A copy paste would be a big time saver here.
