How can I set "from_domain" for all PJSIP/SIP endpoints without edit each endpoint section?

Hello, how can I set “from_domain” for all PJSIP/SIP endpoints of FreePBX/Asterisk?

Thank you.

I believe this can only be done with Asterisk (templates), and adding it to an existing system would involve editing every section.

I don’t believe it is possible under the FreePBX GUI.
