On GStreamer side we have moved some existing pipeline to manual mode.
As we use needs: between jobs, we could simply set the first job to
manual (in our case it's a single job called manifest in your case it
would be the N container jobs). This way you can have a manual pipeline
that is triggered in single (or fewer) clicks. Here's an example:

https://gitlab.freedesktop.org/gstreamer/gstreamer/pipelines/128292

That our post-merge pipelines, we only trigger then if we suspect a
problem.
