Thank you! Yes, that is exactly what I was looking for.
As I am not familar with LPub, I had to add the relevant code via Notepad directly to the LDraw file. Finally I understood the thing halfway; enough to achieve the desired effect.
But I have to admit, that this procedure is, let's say, kind of faked. I think, that is what you mentioned as "sort of".
Up to now I solved this issue by adding blind steps to the main model, right before adding the relevant submodel. Good to know, that there is a way to fill these blind steps with the right content.
