Using merge trains with Jenkins pipelins

Hi,

We are considering to upgrade to Gitlab premium, because we can see a lot of benefit in the merge train feature.
However, we are currently using Jenkins CI pipelines with Gitlab and I was wondering if the merge trains works with this or only with Gitlab CI pipelines?

Regards,
Bjarne

This is also what is keeping my team back for one upping our license. Is there any update on this topic?
