[Feature Request] Indication of linkage between images and corresponding derived series

Indication of linkage between images and corresponding derived series (link icon under the image thumbnail).

Currently, in order to identify which series have annotations (segmentations or RTSTRUCT), the user should either drag individual series into the viewport and see, or select the annotation and drag it into the viewer.

It might be more intuitive if the availability of annotations could be indicated with an icon next to the series thumbnail (to keep it simple, this could be an icon that is grayed out or not depending on whether annotations referencing the series exist, without any count indicator). This icon could replace the current "Instance number" annotation under the series thumbnail.
