This feature set was included in the January update...
Create branch and links to related artifacts
I’m excited to announce that you can now create a branch directly from a work item! The work item form has a new development section that displays linked branches, commits, and pull requests, and helps users take the next steps in their development workflow by providing context-aware links such as "Create a branch". When a branch is created this way, links will automatically be created to the related work item, enabling faster and simpler workflows.
You will also be able to create a branch directly from the Kanban board.
In the same way as the work item form, the pull request details view has been updated to include a Related Work Items section. The Related Work Items section lists all of the work items that are linked to a given pull request and provides a simple experience for adding links to more work items.
