In Vissim 5.40, you could view all static routes that used any particular link or connector; however, I'm struggling to find the same function in Vissim 7. Is this still possible?

Yes, the function is still available. Open the Links list and choose the relation 'Static vehicle routes'. The synchronization button has to be active. In the list on the left side, you can select a link and in the list on the right side you can see which routes lead via the selected link.
