sort subtotal groups
 

I have added 4 levels to a group of data in order to subtotal it. However, I
need to constantly update it with new data and would like the new data to
enter automatically into the 'subgroup' levels?

I can currently only do it if I remove all the subtotals, re-sort and re-add
subtotals. Is there anyway to sort the data so that it will be included into
the subtotals?

Microsoft Excel suggests collapsing the outlines and sorting then but this
doesn't work - it just creates a new 'Grand Total'!

Thank you!!
