Allow re-enrollment for date or number based properties
Absent any field logic of the IF or CASE type, I use workflow to bin numerical information. For instance, if employee count is between 500 and 1000, set the company size to "large".
I would like to be able to set the workflow to run whenever the field "employee count" is updated after "company size" but unfortunately this can only happen once because re-enrollment based on number or date properties is not allowed.
