Add Last 28 Days Range

When comparing data with a previous period, it is interesting to compare traffic on the same days of the week. With the 30-day period this is not possible, but with the 28-day period, since there are 4 full weeks, you can always compare with the same day of the week.

Currently, I can achieve this by choosing a “Custom Range” but it would be much more convenient to have the option in the drop down list of time periods.
