How do I get a splayed window reveal on outside wall face?

[Bill]

I am trying to place windows in a solid wall, and would like to add a splayed reveal on the ouside... but when I click on any of the splayed reveal types, they add it to the INSIDE of the wall. I can kinda correct it by flipping the orientation of the window, but then that ruins my sill/stool settings, brick arches, etc.

How do I get a splay on the OUTSIDE face of the wall?

Thanks!

I'm no expert on the stock library but you may be able to flip the window (sash, jamb, etc) relative to the opening (reveals).
