Offers - Create Them As A PDF Within Taleo?

Summary

Would like to prevent approvers from modifying them during the offer approval process.

Hi - 

When you create an offer and submit it for approval within the system...is there anyway to have that offer automatically be saved and attached as a PDF on the offer approval email that is sent out to the approvers?

Reason I ask is that the way it is now, approvers can open the attachment and make changes (if they wanted to, not that they have).

I know I can save it as a PDF and then attach it before it's submitted for approval...but was wondering if there was an easier way.
