Hi Thomas,
Why you need to go on event basis? is there any mandatory/dependences?
if not then we can handle it your issue with without much hassle.
Lets assume it as you need to run your job hourly once from 8AM to 4PM and your chain will take 40mts every time.
if yes then just create a 8 jobs and schedule them on daily basis.
First job need to run at 9AM - daily
next one 10 AM- daily, go on upto 4pm , like that way you can schedule your jobs on daily basis.
Thanks
