Is it possible to join an MVM Game via the server browser AND activate a Tour of Duty Ticket?

I'm trying to finish a Tour of Duty on the Co-op mode, 'Mann vs Machine'. However, it seems that whenever I join an MVM match using the 'Mann Up' mode, I always seem to get into a server that has high ping (relative to me, anyway).
I can work around that a bit by playing Engineer (a Sentry's aim is calculated on the server side thus they aren't subject to lag issues), but I can't always be Engineer, especially if the team is lacking in other classes.
I can also see MVM games on the Server Browser, with low ping and open slots, however I can't seem to activate the Tour of Duty ticket when joining servers this way. Is there a way to do this?
