Adobe Sign and image

Hi,

I wondering if it was possible to save the signatures that was created by a user and copy it to another machine.

For example, boss has bunch of docs he wants signed.

He/she already has a signature created in adobe fill and sign.

He/she sends you the files to add his signature. You must sign them with your Boss's signature. You dont have his signature

Where is the location that the signatures are stored and called?

Would you be able to copy said signature to another pc so another user can use it?

Or is there a easy way to allow others to sign for you using your signature?

Thanks

K
