How to add/append callback number to text message on Note10+

[Pedro55]

I moved up from my S7 phone to my partner's old Note10+ phone.  Within Settings of the  Message app on the S7  there was an option to (always) add one's callback number at the end of my text messages.  Is there a way to do this using the  Note10+ Message app?

We want to make sure you're able to send that callback number at the end of your text messages. We're going to send you a Priate Note so we can better assist.
