from my customer: "Hello, I just created a custom metric called ÷ 30 taking order revenue and ÷ 30 to get an average daily revenue.... if we are looking at "last 30 days" data. If I change to last 7 days, it would still ÷ 30. I could make a separate line called ÷ 7, but a more elegant solution would be if I could reference the number of days in the formula so I could just title this pin "Average daily Revenue"
