With Visma Addo the signer can approve all attachments at once if the sender has chosen this functionality. 

To add the functionality of approving all attachments at once, you have to:

1. Click on add signer.
2. Enter the information on the signer. 
3. Check the can approve all attachments at once checkbox. 

When the signer receives the documents, he/she will have the opportunity to press "I WANT TO APPROVE ALL ATTACHMENTS AT ONCE". 

Then all the attachments are approved, and when the signer has signed the document he/she is ready to send the documents.
