trvlnmny,

No.  You'll need to select the range manually, then use Data - Sort.  Don't include either
header row in your selection, and tell it you don't have a header row.  You'll have to
select your sort key columns by column letters, not by field name in the header.
Alternatively, you can include your second header row in the selection, and declare you do
have a header row.  Then you can select sort key columns via the contents of that row, if
it's helpful.

Or, you could put a zero in the key fields of the second header (or all of them), and format
them for the same text color as the background to make them invisible.  That way, that row
should always be sorted to the top of the list.
