IMHO you'd do better to create a Custom Document Property or a Document Variable named 'role', for example, then use IF fields in the document to conditionally show content according to which role the Custom Document Property or a Document Variable is set to. Such a field for a Custom Document Property might be coded along the lines of:
{IF{DOCPROPERTY role}= "Manager" "Conditional content for managers"}
You could have multiple such fields for a given role scattered throughout the document. All one would need do the see the documentation for a different role is to update the Custom Document Property then refresh the document's field display. A dropdown content control might be used to manage the role selections.
