When a user reaches the -100009 error code (which indicates there are too many "Must Not" availability entries to be fulfilled), there should be better instruction / next steps. Ideas include:
- Print (lack of) results, with complete caseload information, and certify to administration that listed criteria presents a mathematically infeasible caseload
- Provide easy means to convert some/all of the "Must Not" entries to "Prefer Not". Perhaps a single button click.
- Block repeated attempts to repeat scheduling, without first having reduced number of "Must Not"s.
Likely also applies to -100010.
