This would be massively helpful for our office.
In ALL of our housing projects, we have issues creating repeating dwelling units in Revit.
-We need to be able to create views and schedules of the "unit", like assemblies
-We need to be able to filter the units, like assemblies
-We need to be able to make changes to one instance which updates in all other instances without breaking references, like groups
-We need to be able to copy and rotate units, like groups
-We need to purge unused units when there are no instances, like assemblies
Currently, I can find no adequate workarounds.
