Since this request was made, two other features have been added which touch on this functionality:
1. Every screenshot includes F10-style info in the PNG metadata, so map makers can discover the location of a screenshot even when F10 is not turned on.
2. Users can turn on "Overlay Map" to capture a view and the current map in a single screenshot.

Oh...I just realized the power of F10, which makes this request somewhat redundant. I would prefer a visual of the map in addition, though.
