Thanks for giving LDInstruction a try, and special thanks for your feedback.
The concept of LDInstruction is somewhat different to LPub3D. In LDInstruction, the page layout is defined and all images are created in some kind of batch job. There is a preview per step, but not per page. All included sub-models are created as separate steps but can be inlined by setting the inline option. Maybe take a look at the example in post #22 of this thread.
I could offer some screenshots for the appropriate options. If you don't mind sharing your model, I would create them using your model.
