Hi @yhazem
At the moment that AutomatorWP creates a post launches the following hook:
do_action( ‘automatorwp_wordpress_create_post_executed’, $this->post_id, $action, $user_id, $action_options, $automation );
You are able to hook this action and change the post taxonomies as you wish
We do not offer support for customizations like that since our main focus is the development and maintenance of GamiPress, AutomatorWP and all official add-ons.
Anyway, any WordPress custom development agency or freelance can handle it for you.
If you do not know one, we recommend checking our list of trusted experts we have on GamiPress (all of them are able to work with AutomatorWP) and they can estimate any type of job for you here:

Hope it helps!
