User configurable reports

the plan is to pilot/QA on this on prod so I'm putting it out for code review now. I'm guessing it's easiest to review as a whole, though the commits should represent ~atomic actions.

I think it's good to merge whenever code review passes.
or simply

```python
for choice_obj in self.choices:
    if choice_obj.value == choice:
        return choice_obj
```

(which returns None if there's nothing)
