DWP

How can I send a customized text message to a contact group, using my Google Voice application (or phone number) as the sending number?

Currently, if I choose a different app than my "Default SMS/MMS" app, during message creation, it simply copies all the numbers over to the "To" field of Google Voice. This means that my customized message (using ??G, or ??F) does not work.

Can I have messages sent from DW one by one through Google Voice, so that my form fields (??G and ??F) can be used?

Hello,
Now unable to do so.
If you need to implement this feature. Time to send only one recipient. So that when you send to one hundred contacts. You need to click a hundred times to send. Now I can add functionality to make it work like this.
Googlo Voice API. DWC can send text messages in the background.
I will understand the relevant information.
