for doing that, I create a Group...
I have done that this week so all of my family can be apprised of my wife's condition.
that way, I only need type it out once.
you will need to send it to the same person each time, the one who is first in that group..... ( if you are using the SMS record for the group )
you can select the group manually each time, but that is a PITA....
I just go to 'Josie' and send the message to her, all of the other family members are in the group with her.
