apologies if this is a repost; couldn't find my earlier post

Two questions:

Is there a way to script-edit existing jobs and set the checksum and verify flags? Hand editing a huge number of existing jobs is tedious.

Is there a way to script-edit existing jobs to set reminders. I'd hate to have to re-created them all just to set reminders. (Editing says I cannot set reminders in edit mode?!)

Thanks in advance.
