This is something that we ran across that would be a beneficial feature.  Instead of having to shutdown the process on the SQL side or modify the ReplTableXref procqrec, you could instead flip the flag on the ReplDBXref procqrec field to false and be able to turn of replication processing across the whole database instead of doing it table by table.  This way the state of how you want your tables to be, as far as processing goes, remains untouched.
