Display two maps simultaneously?

Recently picked up an Edge Explore to replace my aging Edge 800. First impressions are positive: device is fast and responsive, screen is brighter and sharper, UI is better, and it's nice to have bluetooth for syncing.

Downloaded some maps, including:
  • OSM (more trails than base map, 82 ft contours)
  • NE Topo (no trails, 40 ft contours)
Is there a way to display two map layers simultaneously? Would be nice to see the 40 ft contours and trails together.

On a side note, I followed the prompts to download Garmin's updated USA map, and it's the best "included" map I've ever seen on a GPS: 100 ft contour lines, most trails, and very clean. I may end up just using it most of the time.
