Summary: Revit Key schedules are limiting in that they don't allow key schedules to be used in other key schedules or duplicated in the same schedule.

Description: Revit Key Schedules limit possibilities of using the key data in other useful schedules. For example, creating a key schedule for Room Finishes.
1) Created a Key Schedule for Floor Finishes with all attached Manufacturer and Color/ Style Data.
2) Tried to create a Room Style Key and use those same key values in that key schedule.
3) Found out you can't add key schedule parameters to other Key Schedules.
4) Excel has the advantage of being able to use a cell from one table in another table, but Revit does not allow this.
