Users who uncheck an auto reject checkbox

Summary

Can users who un-select one of the auto-reject checkboxes be identified?

(In OBI) Is there a way to identify users who have un-checked one of the check-box options below? We have all 3 default to YES/checked for all newly created requisitions. I want to know historically who has un-checked either of these and when but I'm unable to find a corresponding parameter in OBI Recruiting/Admin universes. 

• "Automatically reject all submissions when the requisition is canceled"
• "Automatically reject all submissions when the requisition is filled"
• "When a candidate is hired for a requisition, automatically change his/her status to declined for all other requisitions"
