How can I make gdl that works with the beam?

In REVIT, this is created by linking it with the family.
In Archicad, I would appreciate it if you could tell me how to approach it when trying to link GDL and BEAM.

I think there is no way to link GDL with other elements. Maybe you need to create your API add-ons to link your GDL object to the beam via element GUId.
