i’d like to create a rule that assigns an agent a ticket based on location for every issue except a specific issue or model type.

I kknow I can create two rules for this, one to assign all for that location and then a second rule for who should get one issue that doesn’t apply but that adds the agent as a watcher and and sends an email.  I’d like to avoid the ticket being assigned to the first agent at all.  If there was a condition button in the filter section of the rule that should do this.
