Activity Stream filtered by current user

I'm looking to set up a global dashboard that's shared across our team. For the filter result gadgets, I've found that they can be based on currentUser, but I'm wondering if the same is possible for Activity Stream results. Currently, I know I can assign specific users, but I'd prefer to see results only for the current user. To have generic dashboards we would like to have this.
