I'm not sure about LCR, but it's there in the Directory. The bottom category on the left is "Missionary". Under that, you'll find both Assigned and Serving missionaries. Note that information comes from the Mission Office, so if they're not keeping up, you may not see any missionaries assigned to the ward.
