Creating a custom document type that has sub categories that travel inside the document type. For example a sleep dentistry patient has 9 stages of care(9 subcategories) with required internal and signed documents. The original date would be in the main document type, then all the subcategories (sub-document types) will recieve the pertinent documents. These sub categories (document types) do not actually require the time stamp, but could benefit from this. Multiple documents should be able to be placed into each or the sub-document types.
