Slicer Single Select and Select All option at same time?

I'm working on a dashboard tracking employee metrics, and want to be able to have a tile slicer that shows All employees and their average for some metrics, and then drill down to filter by department. Ideally I'd like to have a slicer that has the options of "All Employees", "Operations", Human Resources", "Finance", with only one being able to be selected at a time. In order to show company wide metric visuals as well as department specific metrics only having to click once. Currently it doesnt seem like this is an option.
