Have been reading about smart objects on this form so I viewed a video on PS smart objects. As noted by the awesome moderators, AP has the ability to do almost the same thing. After developing a photo I saved and then Placed it into a predefined doc for printing. However I wanted to do some changes so I clicked the move tool which brought up Edit Document in the header. Clicking that opened the original so that I was able to do the edits with AP filters which automatically updated the Embedded document. However when I tried to wrap an image around an object with the Mesh Warp tool, it updated the Embedded doc but I was not able to go back and change it. Is that possible?
The other thing that I noted and this could be because of the camera and lens I was using, after going back and forth a few times, the processing became quite dodgy and slow. I was using a Sony A7R3 and the Sony 100-400 GM lens (not yet supported by Afinity).
