The problem with this is that you need to alter the model printed. One thing is to print some yellow dots on a paper, another thing is to print some 3d marker in a model that you know nothing about with the risk to print a defective piece.
And anyway it should be done at the slicer level, the printer still only know that it need to rotate that motor for x steps, nothing else, it has no way to know what the next instruction would be.

That’s what I mean by “if it were possible”
