Disable originating caller id on blind transfer

I am looking to disable originating caller id on blind transfer, and make the outbound CID show up instead. I have tried changing RPID, i’ve removed RPID=yes from the trunk. I am really at a loss. Using Freepbx15. I have edited the External CID Configuration as well to no avail.

Any assistance on this?

I would expect the block foreign CID option in the trunk settings to do this

I was actually looking at trying this. Thank you for the suggestion. Hopefully it will work.

So that worked but that worked at the trunk level.

Any idea how to do that exact thing on the extension level?
