Stairs from rhino to revit

Hello everyone,

I am having problem to export stairs from rhino to revit, it seems that conveyor only have some types of categories, like walls, structure and some other more, but it does not have elements such stairs or railings.
I know I can export stairs in direct shapes and the geometry would be fine, but I like to be able to edit it if I need in revit.

I opened revit, loaded my template, exported with the proving ground/conveyor tab to save as a 3dm file, but when I open rhino inside revit, it doesn’t load all the family layers I have in revit, such as stairs, and other minor categories… It only loads walls, structure and stuff.

Someone knows how to load it all in rhino so i can properly categorize it for revit? Or any other workaround

anyone?
