Team filter based off USERPRINCIPALNAME()

Hi

Is it possible to create a page filter that will filter to the team of the user? e.g. I am part of team XYZ - when I go into the "My Team" tab in the dashboard, the visualisations are all automatically filtered to all the tasks that have mine or any of my teams name attached to it. I have a GAL dataset which I added a custom column named "Team Name" and the person name column has a relationship to my other dataset which has all the tasks and a "Responsible Person" column which the names match back to the GAL person name. 

thanks in advance
