Add Message Body to Button for "Send Text Message" Action

In case anyone else was looking for this, solved with a workaround here:

Glide Translator and Gas Prices

Just tried and it works the same way (which is awesome). To send to multiple numbers, just use sms://[phone1],[phone2]?&body=[message] where phone1 and phone2 are separated by a comma.
