How do i set the team-wide quota on the Dashboard

If you are an admin, the dashboard will show "team-wide" quota which is simply the sum of all of your individual rep quotas. If you are logged in to a rep account, you will only see that reps quota

You can toggle the data adjuster to see how close you are to quota over time, or select "this month" to show how close you are to the entire quota for the month. 

Select "this month" to see the full month quota
