max amount of jobs/characters that can be passed on to -D flag

[camattelaer]

Hello
I've noticed that there is a limit to the amount of jobs that can be passed to the -D flag to control flow. I suspect this is based on the amount of characters the list forms. If i add to many job numbers to a specific job with the -D flag, ts crashes and kills the queue.
Has anybody encountered a workaround?
Could it be possibly to define the jobs to wait for in a textfile?
Kind regards and thanks for any feedback
