Signature classes or pattern recognition.
I have the same type of categories of people repeatedly signing extensive documents. If I could assign a category to signature boxes then I wouldn't have to individually assign each entry. I could assign each person signing to something like "client", "parent/guardian", "company representative", etc. That would allow my preset signature categories to assign each entry to the appropriate person.
