How to trace master branch from bitbucket repo in jira?

[Raghupathy M]

I am able to trace the feature branches created using issue keys. There is no "link branch" option in sprint issue menu. There is only create branch, create commit, build, ,deployment for the feature branches which were created using issue keys. Is there any option to trace master branch from bitbucket repo in jira? Since my production deployment will be on master branch, traceability of master branch is required.
