How do I get part selections in assemblies to show in the feature tree when edges of parts selected?  If I pick a surface of a part it highlights in the tree, if an edge of a part picked it does not.  This is extremely frustrating, as I have to keep zooming in to small parts to pick a surface show the part will show in the tree.  I know the edge is selecting the part, as I can be opened, suppressed, etc., but will not show in the tree.
