Assign Column Cap & Beam-Girder Connection in RAM Elements

I am trying to assign Cap Plate connection to the beams parallel to Z axis and Beam-Girder connection to connect beams parallel to X to those parallel to Z. However, I am not able to assign any of the connections because RAM Element is saying the joints are not compatible. I have tried remodeling the structure using continuous beams for he beams parallel to Z, as well as using rigid offset in Y direction to place the beams above the columns but none of them seems to work.

What is the right step to model and assign such connections? I know I can manually transfer the forces to RAM Connection stand alone to do the connection design but I'm trying to avoid that if possible
