But you can get close - in the VGPS page, you get a list of caches in the VGPS you selected. You can click on any column header to sort by that header, making it easy to find caches of a particular difficulty level or favourite count, for example. You could then delete those items (or everything except those items), if you wish, and then rename the list to reflect its new status. From the Export button you can then map the results.
