Summary: I would like to be able to fill up hill. Sounds kind of stupid I know.

Description: How often have you had a feature line running along, for example, a drainage path and would like to grade uphill at say 2% (50:1) to daylight. I can't figure out how to do this. Negative slopes or grades would work but not allowed.

I'm faced with this all the time.
