How to merge master branch to the feature branch from Merge Request UI?


On GitHub, when you create a pull-request from a feature branch to the master, it’s possible to merge master to the feature branch by pressing a button in GitHub UI if there are no conflicts between them. The thing is that in some Git workflows used by development teams CI build is considered passed only if the feature branch has eveyrthing existed in master. And if CI passed on the feature, but then some changes from another branch were merged, the build becomes outdated and must be run again after updating the feature with the latest changes. According to such worklow it’s inconvinient a little bit to update feature branches from local machine - too much friction for a simple regular task.

So the question is: is there a similar button in GitLab or the only way is to merge master to feature is from my local machine?
