Changing wall preview type in favorite window library

[abode_bon]

Hey guys. I have a library of favorite windows I like to use. In the preview window, they are all set into a generic wall, which is concrete. Is there any way to change the wall type of one specific window to another wall type, like brick or siding? 

I want the wall type of the previewed favorites to be siding in this case, but I see no option to change it, nor have I found one in my internet searching. I know I can just change the generic building material surface, but I have multiple windows that are supposed to be set into multiple different walls.

Thanks for reading.

My window favourites don't show any walls at all.

I wonder if there is a window setting here that is showing, like reveals or casements?

If you double click to activate a favourite and then look at the window settings 3D preview, what do you see?

Barry.
