The AS/400 Job Scheduler will submit to job queue specified in Job Scheduled entry unless you manually submit with option 10. I found this link Submit Job Scheduled Entries that looks interesting.
Not something I need since it is easy to work around by manually submitting the job as I want with SBMJOB. Normally I handle Job Scheduler and many users are unaware. In the case where users need to be able to submit on demand this may be very useful.
Have your best day!
