So, where does this leave me?
as # erfajo pointed out, this can be done manually from inside of Revit by the user. And, I’ll admit, it is easy to do. I was hoping to automate as much as possible for this overall Dynamo solution - to gain buy-in from the users.
So, I am needing parameters associated to the Room objects… the only way I know of doing this is through a Project Parameter… and since you cannot use it in both schedules and a tag, this is the reason it needs to be a Shared Parameter.
