A job array isn’t a collection of jobs. It’s one “job” that can spawn many jobs from it. This means that a subjob doesn’t exist until it starts running. We can’t detach N subjobs from the parent to move into the exec queue. They don’t exist yet. The whole job array has to move.
With this limitation, fixing it as you suggest is quite difficult.
I am not fully up to date on job arrays though. This might be easier than I think. Hopefully our job array expert (@Shrini-h) can weigh in.
