Would be great if we could programatically access trunk merge <PR> via an API call using some token

Since /trunk merge can be run before reviewer approvals and passing CI tests, it would be very convenient to have all pull requests in a repository automatically opt into trunk merge when they're created.

Provide option to control how the merge commit message is generated. Right now it is automatically generated from the PR Description - but with this feature - users could choose how it is generated.
