Adjust addendum functionality to support Salesforce Files
Allow the use of Salesforce Files and Content Documents in the addendum functionality. Currently, it only supports Documents, which are not supported in Lightning, and makes using the app for Salesforce communities far more difficult.
We are reopening this for voting to gather more information about this. If you've voted for this, can you share a little more about how you would use this? If not, please share with other users you think would like to vote for this feature.

The problem mostly is that Documents can only be accessed via Salesforce Classic. With users not using classic anymore it makes the process more difficult to manage. Also trying to use the app in the Salesforce Community does not work properly since they do not have access to documents as an external user.
