We use bitbucket and as per my use case we have two release branches R1 and R2. All members of our team commit their changes to R1, however we have a business requirement to have a release branch R2. We use a pull request to merge R1 with R2 every day. Is it possible to set up an automated merge simply for these branches? We don't want automatic merge to impact other release and feature branches. Can I use the feature of bit bucket "Automatic merge" for my use case?
