It would be helpful to have a toggle (or some other way to make a choice) in the columns section of the report builder: Alpha or Sheet Order.
Most reports mirror the layout of the underlying sheets to some extent, so it would be helpful to have the column list sorted in the same order as the columns appear on the sheet (especially when building a report from a sheet with a lot of columns). At other times, the alpha sort is the most helpful.
When selecting which columns to include in Reports, allow us to view columns to select by column ORDER and not alphabetically only.
It can be cumbersome to look for each of the columns you need when most of the time you put the ones you want most in the beginning of the sheet.
