Designer to Painter bridge

I mean  not just like “export to PSD”   but rather an ability to  re-export  to certain  layers while not overwriting  Painter file entirely  and all the work  done there .  In a word  a way to cash selected nodes rasterized   in  Designer and update them as layers and masks   in Painter .   Doing sbsars is such a pain. 

I could do all this manually probably  by exporting a set of outputs , bring them to painter layers   and update on demand there  but would be nice to have it all automated one click solution .   Maybe some python script in Painter or something . 

  I think chat GPT  could easily do such script for Photoshop  but I never managed to make it to do  anything  working for Painter.
