Bump mapping in surfaces in OpenGL

Perhaps I am losing my mind, but I seem to recall a time in which ArchiCAD could handle 3D display of things like blockwork mortar joints via an alpha channel within a surface texture, allowing the remaining bricks or blocks to have colour adjustable via colour picker in the surface editor - and that the result worked in the standard OpenGL 3D editing window environment, not just in rendered views.

Am I deluded? In ArchiCAD 28, How can I have dynamically a colour adjustable blockwork surface appearance in the 3D editing window? (without having to go into photoshop to create every colour permutation via multiple bitmap texture definitions)

Also, as far as I can tell, none of the surfaces in the additional surface catalogue appear to work using bump mapping, though it looks like that is intended?
