Yes, you can do this via an Export Script. See the --get_options documentation, specifically the
--modify_url callback. You can also inject jquery and your JS libs at this time.
As you noted, the DoubleClick Studio export script does this. You can see that their JS script is added with
insert_at_head_start and functions in
--get_options are added in the
I'm happy to help if you have any other questions, or in doing this if you have any feature requests on the Export Scripts.
