Can we know that a user/Approver reviewed the journal data\attachments before clicking approve

Summary:

Hello,

We have below requirement from one of our client.

The question that keeps coming up is how do we know that a user reviewed the journal data \ attachments before clicking approve. We would like to see if two thing can happen.

1) Can we add fields for a user to check off stating that they reviewed everything per policy?

2) Is there a way to see if a user opened an attachment \ file on the journal entry?
