I don't mean this to come off as insulting considering I have a PhD in Physics, but honestly using the PE is quite simple. Register the object, apply a force, watch it go!

The problem is that you are trying to workaround the 1 object commercial limitation; hence all of your problems have to do with the workaround and NOT the PE.

Conitec will not make a template to accomodate this workaround since a) it would defeat the purpose of the limit, b) they aren't working on A6 anymore, and c) unlimited physics is standard in all versions of A7 anyways!

So my advice to you is upgrade to A7 and use the PE without any work arounds. But if you stay with A6, not that un-registering an object is merely a null set_type call.
