You could use a union query. This seems to give the results you want...
You have to use SQL view to create a union query. Create the main query (you already have that). Then add the 2nd query. It has to have the same number of fields. Doesn't matter what the field names are . Here is an example of the query I used to test this:
Code:
SELECT [010_Clients].ClientID, [010_Clients].FirstName, [010_Clients].MiddleNmae, [010_Clients].LastName, [010_Clients].Available
FROM 010_Clients
UNION
SELECT "" as A, "" as B, "" as c, "" as d, "" as e FROM 010_Clients
ORDER BY [010_Clients].LastName, [010_Clients].FirstName;
Note: The ORDER BY clause is after the second query; the field names are taken from the first query.
