Multi column sorting

Hi alex,
When i do the sorting for the first time i get all the data sorted.In my proj i have 4 columns(type, subject, date, name). After the sorting is done i have few cells where the data gets repeated. Even the sorting needs to be done for these repeated data based on another column(say date here) for the first time only. I have seen a reply for this in the kumaran topic given by you but couldnt it be possible to have it for the first time rather than clicking on any columns.
