I haven't heard of a GPS unit that allows the user to set some sort

The CNX-80 / GNS-480 has it. It's called "Parallel Track". You tell
it if you want to fly left or right of course and by how much (in
1/10's of a mile IIRC), and it invents a new course line for you to
follow.

The Trimble 2102 has it, and so do most other units.
