Saved 3d view ortho projections/frames + paste into bitmap node

Would love a feature when we could  save an ortho projection , like put an ortho camera  in 3d view , then copy the view into an  image editor , paint and paste back into bitmap node.  

 it's all almost there alredy , I see top, font etc cameras  . it just need to be exact  frame, saved in a special list    rather than camera angle   .    Then we  need an option to paste it back . Something like right click , select a saved frame/camera and "paste"  which would bring a bitmap node assosiated with exact projection.

My guess it should be much easier than  bringing Painter  ability to Designer .   And I would still prefer  it because to be honest  Painter brush system is  not a greatest one . 

Pretty sure Chat GPT 4 could make me such python script that woulld do it for Blender . Too bad  I need  it  in Designer .
