Vision Power Table Footer

Does anyone have a trick up their sleeve for how to add a footer to the vision powr table?

In the perspective table there is a convenient option where I can add whatever formula I want to sum up values in each column.



When I’ve needed to sum in Vision I’ve either done a separate table that creates a sum using the original tables dataset or if I only need it for a couple field then I’ll use a numeric label and sum the values for the column I want there.
