Ram Masonry Wall Module - Flanged Walls

Is there a way to design masonry shear walls with flanges? I see that the flange option does not provide a wall design for the flange?

Is there a way to design the flange so that reinforcement is ineffective for compression and effective for tension?

Also the program seems to limit the flange to less than 6t, and adjusts based on the length of the wall, is this correct?
