Can I turn a map from the player maps section into a new page?

I'm running Out of the Abyss, and I'd like to turn the map of the underdark player handout into a full sized map that the players can move their tokens around on... Is this possible?

if you select an image and generate a preview with the Z key (or in the case of a handout just click on the image), you can right click on the preview and download it. Handout images are typically lower resolution than map page images though, you may not get great resolution. You can then upload it as its own page. Edit: If you are talking about the map in "Underdark Travel", it should be high enough for tracking purposes.
