Diagram Type ~ Submitter Text Box
This provides a predefined Text Box containing Submitter details. The Text Box itself can be copied into any Chart or Diagram or Custom Diagram Type definition. It relies on details entered via the Submitters tab of the Records Window and defaults to the Submitter with a Record Id of 1 but that can be edited.
(When opening this Custom Diagram Type it will ask for a Root Person but it is irrelevant who is chosen.)
