You can!

Use the “Add Geo-Shape” button to query for the shapes we’ve got in our database. You can either highlight these areas or invert them to create a map focusing only on the shape you’ve selected.  Adding multiple shapes is supported as well, and since we’re all about flexibility, you can choose whatever colour you like for your shapes (or the shading if you’ve inverted it). Tip: Use shapes to create layer masks in Photoshop or Illustrator. (Each shape will be a separate layer in PSD and SVG files.)
