Generated job name: customize or omit the prefix

[hzh]

I am testing this plugin for our Jenkins Gitlab integration. So long it works exactly the way we want, except one tiny issue.
I have configured the plugin to auto generate jobs for new branches. The name of the generated jobs seems bo be either "<template_job_name><branch_name>" or "<gitlab_project_name><branch_name>". I would like the job name to be simply "<branch_name>", but could not find out how to configure. Am I missing something obvious? Or could this be a new feature?
