Not with the current version.
But the way i'll do it, is register a custom event 'send_sms_after_create_order' then trigger the event within the core. This way i've only modified the core with a single line of code and its much easier to fix when theres an update. Have a look at https://docs.tastyigniter.com/developer-guide/event-hooks/
....Life will be so much easier with future versions :)
