Could the block depiction be added through the Fill "Custom" selection via the patterns file? If added.
Something like this.

I'm building a 8"x16" regular masonry block wall. Is it possible to have this depicted on the floor plan? In the wall Type Definitions box under fill, there is no choice for the 8x16 CMU.
Thanks!
