We've been using a home built merge tool for well over a year that:

1. Runs git log against a pair of branches to determine if merges need to be done
2. Creates Pull Requests in each Bitbucket repository where merges need to be done.

After configuring Default Reviewers in all of our repos recently, I noticed when running our merge tool that when the tool creates the Pull Request, the configured Default Reviewers do not get assigned. I looked in the Rest API docs for creating Pull Requests and do not see an option for enabling this either (but we are running BitBucket v4.9 at the moment).

Does the REST API in Bitbucket v5.1 support Default Reviewers being assigned automatically when creating the Pull Request?

Thanks,
Carl
