Create an Area?

How can I create an area to avoid?
I'm using MapSource and HomePort with Win7.
I've established Proximity Alarms for individual objects to avoid, but want to establish an area to avoid, based on Lat/Long. The area is a controlled fishing area. Once plotted on MapSource or HomePort, I want to download it to my GPSMap 76, GPSMap 198C, and eTrex Mariner.
With that area displayed on my GPS, it would be easy to avoid without having to refer to my paper chart and Lat/Long.
