[c-nsp] Policy routing visibility in the CEF table

Now this may only be on certain platforms – or not exist at all.
I was sure in the past I saw a show command for the cef table that let you see if policy routing was being used on a source destination pair.
No one except students actually likes policy routing in the real world...but at certain places I am stuck with it.
As policy routing does not show up in the routing table, and looking at route maps is cumbersome with large config – I think I once used a command that is similar to the command used to check the CEF load balancing output interfaces when using ECMP
Does anyone know/remember this – or does it not exist? (in IOS)
sh ip cef exact-route SRC DEST (on a sup2t)
gives me the output of the adjacency (interface, nexthop) it is the normal outgoing interface in the routing table.
Any ideas? Or did I dream this?
