Is there a Key in way to assign Catalog type and Catalog Item

Hello all:

I'm trying to automatize the process of assing Instance Data to Meshes in Openbuilding.

I've realized that the keyin "dg add data" opens the Add instance Data tool. But Does anyone know how to select the Catalog type and after the Caltalog Item inside through a key in?

With those commands the instance assign process could be automatized through a VBA Macro.

Thanks in advance
