Unique ID for each document
From this knowledgebase article (https://support.aodocs.com/hc/en-us/community/posts/206157743-Ability-to-create-a-view-that-spans-document-classes) I understand there is no straightforward way to set a property that is visible across multiple document classes.
We have multiple classes of documents and want to have a unique number assigned to every document regardless of class. Is there a way to do this? If not, would you consider adding an automatically generated unique document number field to the global properties that I am able to see across classes?
