Grouping linked shapes

[Barendjvr]

I have created a rather big process flow. There are several end point and a
lot of shapes linked through the process. I would like to isolate one
endpoint and all of its linked shapes. But to go and do this manually (by
grouping all the linked shapes) would take a long time. Is there a way of
getting all the linked shapes into a group automatically?

Thanks
