I have a dimension called Account Property Count

Levels are:

Property Count

Group Level by account names (this level is not visible)

Account Name

This is ok. I want to create another group level for Property Count because
I want to group these in a range but not have the group level visible. I
cannot seem to accomplish this task in the dimension edtior. Are you aware of
any custom grouping formula I could use to group the property count level?
