Ability to show/hide annual pledges in "Pledge Growth" spreadsheet

I recently enabled annual pledges and to be honest, they’re kind of making it hard to visualize trends in my pledge growth. For example, the month that I enabled and advertised annual pledges, it looks like I experienced double my most successful month’s pledge growth — but obviously this growth is not a monthly reoccurrence.

It would be great if we could choose to exclude annual pledges from the “Pledge Growth” chart, or better yet, to view them as an evenly distributed “monthly” charge extrapolated into the future. This would just make the data easier to interpret from a bird’s eye view, in my opinion.
