Hi @michaelgmccune ,
What you are asking for totally makes sense and we are aware of this limitation. Currently, we are working hard on a Mapping Tool 
that will (eventually) allow us to get rid of this limitation and better enable this kinda workflow.
With this tool, you’ll be able to create native Revit elements from your existing geometry in Rhino. This will happen either by using existing elements from Revit or creating new ones using Rhino geometry. Users will have the option to convert Rhino Attributes to Revit Instance/Type parameters.
Your feedback is more than welcome. Give it a try and let us know what you think.
