No. there's no relationship between a digital signature, and any block/stamp/object in the drawing. Anything you see in the drawing is irrelevant to a digital signature - what the digital signature does is prove that a document has not been altered in any way since it was signed, and that it was signed by an account that had access to that specific digital signature. Even a single bit change will change the hash of the file and invalidate the signature.
If the 'certification' you're looking for is supposed to be visible in some way, then a digital signature is not the answer.
You'll need some customization to handle that -- possibly a routine that on-open deletes the certification stamp, and a modification of the same that inserts a fresh one. But nothing OOTB that handles that kind of thing.
