Culling: Grouping function across the whole project

I often cover events and concerts. Especially at concerts there are a few standard positions and standard scenes which I come back to several times throughout the event. This results in several sequences of "similar pictures" spread throughout the whole event (or project) and interrupted by other images and sequences.

Unfortunately the grouping function of the culling tool only catches a sequence or group of one occurrence. If there are other images after a sequence the grouping function does not find another sequence with similar images.

As a result I have to mark one or two images of every sequence for processing. This gives me way too many similar, selected images of the same kind because it is difficult to compare images manually when they are interrupted by other images. So I rather mark and select too many images than overlooking one.

However, if the culling function could analyze the whole project and collect ALL the similar images (thus arching beyond the other non-similar images in-between) I could compare ALL the similar images and select one or two of them all.

This would reduce the number of images processed and save my time (and cut endless night shifts a little shorter).
