There are times when a provider might need to add their signature to a document that is assigned to a different provider. Now, documents will have Sign As options for the chart item provider and the logged in provider (if they are different). This feature is also available within the PDF Editor where there is now a provider name dropdown where the user can choose which provider signature to add. 

If a practice does not want to use this feature or does not want to allow certain roles to have the multi-user sign option there is a new permission called 'Provider Only Signature'. When this is checked on the logged in providers signature would be an option.
