Adobe E-Sign & Signature Block

Why can't I resize the Signature Block option like I can the Signature option in Adobe E-Sign?  The Signature Block covers up required information on court forms, which is a problem.  I like the fact that the Signature Block provides the Name, Date, and Email address of the signer but given the size of the box, it is mostly useless to me.  I note that if I send a document to a client to sign outside of our company, their signature will automatically include the date and time they signed.  I want this function for all signatures.
