How to stop emails send to prepay auditors?

Hello all,

We are interested in using the prepay audit for expenses. We are using the standard process ID ERApproval and it all works fine.

We have enabled the Email check box, so that the managers are getting an email when they have to approve an expense. After their approval the expense will route to the prepay auditors. The problem is that they also receive an email that they have to approve an expense. Our prepay auditors have told us that they don't want to receive these emails.

Is there any way we can stop the emails being sent to the prepay auditors?
