My understanding is sql ppm directives are not sql/sql_id based rather

Still my question is
I know I can tell from dbms_xplan cutsor note section but is there a bulk way

There is also a good article in DBA hell:

And my favorite is Lodovico Caldera:
http://www.ludovicocaldara.net/dba/sql-plan-directives-problem/
Finally, there is a little known and infrequently visited site at
https://support.oracle.com:
How to Identify Specific SQL Plan Directives In Use For A SQL Statement (Doc ID

Happy New Year
