This suggestion occurred to me just recently. It is a minor modification for the Burrow top quilt -- the one with the (standard) snap-close footbox -- when used in a bridge hammock such as Warbonnet's Ridgerunner.

If the last (bottom) two snaps are switched left to right, so that the male and female components are opposite from all the other snap pairs, then you can easily attach the bottom two snaps together on each side (making a "collar" and shortening the quilt). This allows you to snap the quilt onto the Ridgerunner's spreader bar (if its bug net is stowed), or to loops you make in the ends of the two strings used to stow it (if not). It may work with other bridge hammocks as well.

You can still snap the footbox closed as originally intended, and more easily keep the quilt off the ground when its too hot to put over you.

This modification should neither cost much (if you ask when ordering your Burrow), nor reduce the effectiveness of the footbox much, if at all.

Unfortunately, I didn't think of this until several months after I got my Burrow...
