Signatures at multiple positions in the PDF

Signatures at multiple positions in the PDF. This is mainly a Verification & Validation document,

where signatures will be applied for each Test case present in the document(4 to 5 signatures in a single page).

We have observed that applying a signature for one place involves lots of steps and saving of file each time.

This leads to lot of effort when we have to perform 500+ signatures for a single document.

So do we have any mechanism to get the pre-stored signature with a single button?

Note:

We are using Acrobat 11(Adobe Reader 11)

Steps that we are using for getting a signature are:-

Precondition:(Steps involved in creating Signature)

Steps involved in placing the signature:(It will be performed each time a signature is placed)

Click on Place the Signature button

Identify the location for the signature

Enter the password

Click on OK

Save the file

Thanks
