No way to configure gitlab webhook in multibranch pipeline for detected branches(Individual) from Gitlab repository

[Sagar Utekar]

I am using multibranch pipeline for Gitlab repository, after a lot of efforts it is now showing all the branches from repository. But now I am facing issue as there is no way to configure Gitlab webhook for individual pipline in multibranch pipeline, though it is showing option to build trigger when there is any change on gitlab,etc but there is no option to save changes, as I am creating secret token for gitlab webhook, there should be way to save it, else it will not reflect chnages and start build for that pipeline. 

It is also not triggering build on any branch pipeline on change in repository.
