I am trying to find a way to trigger multiple jobs running on a remote Jenkins server in parallel. Using the parameterized remote trigger plugin, I can only trigger them sequentially which takes very long. 

The parameterized trigger plugin allows jobs to be triggered in parallel by listing their names separated by commas. This is not allowed in parameterized remote trigger plugin. It would be useful to add this functionality. 

Another way to trigger remote jobs in parallel could potentially be done via the multijob plugin, but looks like the multijob plugin does not support triggering of remote jobs.
