Cull sort feature

When using the cull feature and grouping similar photos, it would be very helpful to have a "sort by" feature or a way to filter out the singular photos that have no similar comparison photo to help with workflow. When doing shoots of sporting events, a catalog may have several groups where I used burst mode to capture action shots but also several portrait style shots of individual players. When I use the cull feature on my catalog, having the ability to remove the "1 of 1" groups or to sort based on the number of photos in each group would be very helpful to intentionally cull out (or at least label unwanted photos) duplicate or near duplicate photos.
