[How is it possible turn on and off IgnoreRecordRepeat in OnJobstart?]

How is it possible turn on and off IgnoreRecordRepeat in OnJobstart?

I want to be able to turn on and off the Ignore Record Repeat (and many other attributes of the JobOptions.) I have tried FusionPro.Composition.JobOptions.IgnoreRecordRepeat = false

and many other combinations and nothing has worked.

Any ideas?

 

(Eventually, I want to control CropMarksInBlack, IgnoreRecordRepeat, PageInfo and use a different imposition file.)

 

Thanks.
