I think I found another way for Pocket Sliding Openings with threee parts.
First I use an empty opening double the size of the door or window that will be placed.
I place the three parts (door-screening protection-shutter) by adjusting the position and the reveal depth.
Finally I have designed a complex profile wall with a gap in the core that will be used as the pocket in the empty opening that was placed in the initial wall with the openings.
This is fast because you can immediately adjust the pocket wall (complex profile) according to the type of the opening (door or window).
The only proble is that although there are window shutters, the library does not contain any door shutters so either youuse the shutter object or use window shutter for doors too.
