Hi Remi,
Glad you’re enjoying the plugin!
We’d welcome any feature requests you might make with regards to extra filters – right now though you could explore making use of WordPress’s own wp_insert_post filter (actually a number of filters/actions fire when the ticket is created) or even prepopulating the ticket name field with a little Javascript magic.
Could be neither of those approaches is exactly ideal, but they certainly ought to provide the basis of a working solution.
…and please do post a feature request if you’d like to see more specific hooks in a future release 🙂
Hope that helps!
