Is there a way to lock terminal's title?

Sometimes there're lots of different sessions opened in own terminal's tabs and it's rather desirable to have theirs initial titles (named by session name) locked since local title tweaks make those sessions indistinguishable. It's obvious that controlling all the bits and pieces of remote software running is too wide task to be accomplished in reality, so the most suitable way would be setting a knob prohibiting any further changes to a title. I doubt there's such a knob, but who knows?
