We use Jenkins for our Continuous Integration and we configure our jobs with "job in amount" or "job in aval" parameters.
This configuration launches automatically one or more jobs.

But when we launch manually a job, we want to have the result as soon as possible.
And when all jobs automatically launched are in the pipeline, the manually launched job will only be executed when all other jobs are finished.

It would be more convenient for manually launched job to have a higher priority than automatically launched job.
