Is there anywhere I can find more official and unofficial additions to LO scrapbook?

Cheers

Hey,
Just wondering if there was anyway of adding details to your wall thickness in a section in LO.
Such as adding insulation, platerboard, wall joists etc. Without having to model all of the details in SU. Because it would be much faster to just sketch on the details on the sectioned wall in LO if it is the correct overall thickness. With the correct insulation squiggly line etc etc..
Can anyone help with this please? It would cut down my work a lot hehe.
