How to trigger and show status on multi repositories on the same pipeline

### What feature do you want to see added?

Hello,

We have found a legit use case for the plugin, which I explain below.

We have a GitLab repository containing the source files of the project which we will call source-repository and a GitLab repository containing the continuous integration for the the source-repository (build, test, deploy) which we will call ci-repository.

Our need would be to clone the ci-repository via Jenkins web app and then the possibility of choosing:
- We would like to select the repository where the status will be displayed.
- The automatic triggering of the pipeline (push, mr, tag) from the source-repository and the ci-repository

Another case is a project composed of several modules separated in different GitLab repositories and a common CI is needed.

Is this functionality already possible or is it possible to implement this feature?

Thanks for your help.
