share how they provide auditors proof that the firefighter logs are being reviewed

I am running GRC v10.0.  I am having problems tying firefighter event logs (Reports & Analytics/Firefighter Log Summary log report) to workflow logs (transaction SWI2_FREQ uses table swwwihead) that show that the firefighter event was reviewed by the owner/controller. 

Its seems that I have more events that I have workflow logs.  Can anyone share how they provide auditors proof that the firefighter logs are being reviewed?

Thanks,

Kerry
