Treating multiple rows as one, for sorting

[uj4]

Is there any way to treat multiple rows as one row for sorting purposes? In my spreadsheet each item has two rows of information. I would like to be able to sort these items, but need to make sure that both rows remain associated.

Thanks for your help.

Id probably try to add a column, where each pair of row gets a 1 and a 2. What about the secondary sorting, that you see in the sorting dialog?
First sort as you would, secondary sort the new column with the 1 and 2s
