From what I understand, there currently is not a way for anyone from user to admin/owner to see how a column is being used in an existing report by solely looking at the column itself. I am in the process of cleaning up one of my grids and noticed that the below prompt appears when I select a column to delete. Having additional visibility of if the column in question is actively being pulled for one or various reports would be very helpful. That way I know to edit a report before deleting the column or realize that the column is still needed.
