Designate Total Columns in Waterfall Charts... like you can in Excel.

Excel allows the ability to right click on a particular step in the waterfall and designate it to show it as a total amount in the process. This seems to be possible using the breakdown capability, but it adds an additional level of complexity, and also forces you to breakdown each total by all available breakdown types, leaving it to be a fairly larger chart than it otherwise needs to be (i.e., showing zero lines a lot in my case). The ability to designate what to total and where would be great.
