Similar to an inbound call webhook, would it be possible to add a pre-call webhook for scheduled batch calls? I have to assume this would be a heavily used feature as I currently work with multiple companies where we have a follow up call sequence and use the schedule batch call api to schedule follow ups if the caller did not answer the first call. The scheduled call is usually a few days later so if a human on their team ends up speaking with that customer then I want to cancel the scheduled batch call so the AI does not call them anymore. Is this possible? If not is there a way to add this somehow thought a pre-call webhook that fires at the scheduled batch call time?
