Link attributes to the model in OpenRoads

HI! I'm an engineering student and I'm using the software OpenRoads for academic purposes. I have a question about how to link to the model some types of attributes. Can I link to my project information on the characteristics of flooring materials, safety barriers and other types of non-graphic attributes? In wich way?

I tried to use item types and OLE (utilities) but I can not use them.

Thank you.
