Configure "Query Builder" for Theta-Style Joins over ANSI-Style Joins

Question

Can SQL Developer be configured to auto generate theta-style joins instead of ANSI-style joins when building queries? This happens when I generate a query using the Query Builder and then switch over to the Worksheet tab to see the SQL code.
Sample code:
Theta-style join syntax uses commas to separate multiple table names and creates the joins in the Where clause:
SELECT c.name
FROM instructors i, courses c
WHERE i.firstname = 'Mary' AND i.lastname = 'Williams'
AND i.course_id = c.course_id;
ANSI syntax uses the JOIN and ON keywords instead:
SELECT c.name
FROM instructors i JOIN courses c
ON i.course_id = c.course_id
WHERE i.firstname = 'Mary' AND i.lastname = 'Williams';

Hi Wes,
There is no preference for configuring this that I know of, but Query Builder is fairly clever about detecting your flavor of SQL from the worksheet then sticking with it. If you design it graphically, the default flavor is ANSI, but QB seems to respect any worksheet edits that switch it to another flavor. I wouldn't vouch for that absolutely, but perhaps it's behavior you can take advantage of.
