You can use Virtual GPS.
Click on the degree sector, it will show you the caches on the map, then click on the button with Virtual GPS on the left of the map, choose the select tool, draw a selection around the caches you are interested in, click on the VGPS add button and the caches will appear in your VGPS.
This would be nice to have some better guide. Let me know if some of the above is not clear (note that VGPS needs active Membership).
