Passing Host's Instance Parameter to Nested Family (w/o Shared Parameters)

If you have a nested family, is there a way to assign an instance parameter to the host and have that propagate to each nested family's instance parameter?  I know this is possible via Shared Parameters if you associate each nested family's parameter to that SP, but what about for the out-of-the-box instance parameters such as "Comments" or "Mark"?  Ultimately, I want to be able to create a schedule of all nested components and have them read the same instance parameter without having to tab-select each nested piece and enter the parameter manually.

 

For example, say we have a cubicle as a nested family which contains a desk family, computer family, file cabinet family, chair family, etc.  I want to be able to place an instance of the cubicle in a project, assign "Building A" to its instance Mark parameter, and have each nested instance display the same "Building A" in its Mark parameter.  That way I can create a schedule of all components that are associated with Building A.  But when I tab-select a nested instance, the Mark parameter is blank.

You might be able to do it via Dynamo or some add-in.  

 

To do it in Revit manually, you Tab + Control select each and all instance of nested components within one parent family and enter Mark for all of them at once.

Attached a mock-up (Revit 2024) of a parent/child family that can schedule the parent or the children and indicate which building they belong to via the parent. It uses "shared" nested families and a shared parameter "Building" in the parent and nested children.
