What's the practice for Github cascading merge?

Question

Is there any option or practice in github which provides auto PR cascading like bitbucket (https://confluence.atlassian.com/bitbucketserver/automatic-branch-merging-776639993.html)?

Basically if I merge a PR to a release-candidate branch, it will also merge the changes to master as well.

Github doesn't have this capability at present and this feature is not mentioned in Collaborating with issues and pull requests help section. You can try to implement it with server-side hooks but it's not provided by Github as a repository configuration option.

Perhaps that's because Github suggests GitHub-flow which unlike Git-flow doesn't use a separate release candidate branch.
