There are two ways you can do this with the new plugin:
1. pin a build to a label (under the Populate Options)
2. use a parameterized build, click on the 'Build Review' button and specify a label or change (the other fields are optional. You can also call this as a url endpoint (see Markdown file for details).
Interesting feature; please will you provide me with some details on a typical use-case? If you rely on any other Jenkins plugins as part of the use-case let me know.
