Sort by Shortest Distance to Next Object

I've been using the observing lists in SkySafari (versions 5-7) pretty fanatically, and the myriad ways to sort lists is quite extensive. One that is NOT in SkySafari, and probably should be, is the ability to sort by objects' distances from each other on the sky. While it's nice to sort by transit time (for example), it would be useful simply to have SkySafari proceed to the object closest to the one that's currently being viewed, rather than one that may be thirty arcminutes to the east but 60 degrees of declination away.
