Display taskboard for current user

I'm trying to display a taskboard for the current user within the RTC web client. I've been able to create a taskboard that groups by user, but that's still a little noisier than I would like. I see that a filter expression can be added, but I can't get it to work for the owner attribute. I've tried owner:"Current User" as well as specifying my name, but neither filters the taskboard. Has anyone managed to get this working?
