Associate a type code with Decline option in Open Enrollment

Currently, the "Decline" option in the benefit groups maintenance is not available in the setup, and is presumable hardcoded. I am requesting it be made available to be set up as one of the many choices within the benefit group, and allow it to be tied to a type code. We would set up a zero rate type code, and associate it with the "Decline" option. This would allow us to run reports on those members who had declined medical coverage. Right now, we have to arrive at that answer through a process of elimination.
