Automatically Generating Roof Wind Loads ( WLX+R, WLY+R , WLX-R, AND WLY-R )

[BiagioCaruso]

I know Risa 3d can automatically calculate my wind loads (WLX, WLY, WLXP1, WLXP2, WLYP1, AND WLYP2) and place them in my basic load combinations for me. Does Risa 3D have a way of calculating my roof wind loads automatically( WLX+R, WLY+R , WLX-R, AND WLY-R ). If it does not what would be the best route to hand calculate them? I just have basic flat roofs. Thank you
