export ProConcrete to IFC with an extra data

Hi,

I would like to add some „extra” information to the rebar definitions that will be exported to IFC, e.g. add name GROUP_1 to different reinforcement sets (beams, columns, single bar, etc.) that will be “visible” in IFC file (custom data record). Is there any way to do it using ProConcrete? Is Assignment tab a good place to search such a possibilities - Part family/Description?  May these records(fileds) be exported to IFC?

Regards,
Bogdan
