Access -Process Overview- from unstructured box

The -Process Overview- that can be accessed from a box view by clicking -Parent Sample- is very helpful and an appreciated tool. Unfortunately it seems that it cannot be accessed for a sample in an unstructured box, which is particularly troublesome since most of our users' have parent samples in unstructured boxes. They would very much like to be able to find the parent sample and then get an easy overview of (and access to) related samples. Perhaps the Process Overview could be added to the right-click menu?
