I don't think it can be done...
Suppose you want to sort on AxBxCxDxE
You need to sort on the lower importance columns (D and E) first and then on
the higher importance (A and B) to get what you want

Does anyone know if there is a way to add more sort fields to the sort dialog

if I could sort four different columns.
