Automated SMS messages to guests (Via SMS messaing pilot)

I’m enrolled in the SMS messaging pilot. I really need the ability to select SMS as a delivery method within automated messaging rules (such as 'Before check-in' or 'Before check-out') so that guests receive these as text messages so they get this instantly and there isn't a delay or issue with them not getting the message that could occur through the channel’s native messaging system.

The SMS messaging to guests works well, but having this automated through the automated messaing is where the SMS messaging would be most valuable.

Is this expected to be added in the future and any idea of a timeframe?
