Marking the Box on Your GPS

[Cameron]

I've got a Garmin Aera 500 in my Acro Sport II. I've been making alot of feeble attempts at the 2012 Sportman Sequence and I've thought many times, it would be nice to really know where the edges of the box really are rather than guessing. I then had the idea that I might be able to mark it on the moving map of my GPS, but I have no idea how.......... or if it can even be done by someone other than Garmin.

Any ideas?

How do the rest of you without a marked box practice?
