What he mentioned is a different thing, which is create a new Area scheme under Area and Room computation, where you see Gross Building, Rentable, etc. as shown below.
That's not what I was talking about. That would be silly. That would require creating a new Area View as well. Unless that's what the OP wants. In that case, then yes; create a New Area Scheme and Area Plan. But, what I meant was why not create a New Color Scheme Entry? In other words, populate the existing list with other Color Schemes -- named ones in this case -- and assign the new named color scheme. The old name just wouldn't be "in use".
...then use your schedule approach to assign the names (from the drop-down) is necessary.
