sorting by items not visualizing

Hello,

I am user of Windchill 11.2 and CreoView 6.0.  What I am curious about is when we open up structures from Windchill into Creo View, sometimes there are items that will not visualize.  Which I know there is many reasons for this as I have become proficient at figuring this out.  The problem I have is finding these out.  Some of our structures can be over 1500 branch links and I really don't want to click through each branch link (or expand by all levels) to find these.  Is there a way to search or sort by items without a checkmark next to the item?  See picture of example.  Thank you for any feedback.
