"see custom field" and the create ticket page

I’m using RT 3.6.1, and need all users to see all custom fields in the
ticket display. Some of these CFs are automatically populated by a
scrip, so they are not needed on the ticket creation page. How can I
hide a particular CF during ticket creation, without using the ‘see
custom field’ permission (so it still appears in the ticket display)?

I’ve tried modifying create.html, but the code that handles the rendering of custom fields is hard for me to decipher. Any help would be greatly appreciated.
