Feature Summary

We have the ability to relaunch jobs on either failed hosts or have it run on all hosts. However, when relaunching a job, we cannot edit the variables that were used to run the job.

It may happen that a job failed because a variable was wrong, or that one of the variables controls output and we need it for better debugging the failure (both have happened for us).

Please add the ability to edit run-time variables when relaunching a job.

Allow updating of variable values to a relaunch modal/page/dialog box.
