Create Total columns "on the fly"

As opposed to relying on either selecting a cumulative view or having to add a number of formula columns to a board in order to display a total of for the displayed columns in a bar chart; I would like to propose adding the functionality to create a total column(s) on the fly. The user would have the ability to select the column values that contribute to the total and the name of the column. This would provide the viewer with the ability to observe both the individual values and the total in one view without having to select the cumulative view or creating additional formulas.
