Select irregular shape for 'export view' to GARMIN OREGON

[3034]

With the 100 tile limit, Mtn Biking (cover lots of area in 1 day)  and my desire to have .003 color maps
The rectangular selection method  picks up to many areas that are not useful.
(for example a riding area on one side of a meandering river athat your not going to cross at all)
I would like to
1. draw a polyline around the areas I want exported
2. select export view and choose .003 color  (or any map type) to KMZ  to garmin GPS


or as an alternate method of selecting
how about multiple rectangular areas to build a 'set' then 'export view'

This is a good idea, and one a couple people have requested as well.  I will think about the best way to do it, but it does seem like it'd be very useful to be able to select non rectangular areas -- maximize the 100 tiles.

Thanks.
