Multiple Signature fields

For now there's the option to sign a quote when approving.
But it would be better if there's a box that can be placed in the quote or in the contract templates where a signature is required.
To make it even better, it should be possible to place a signature box on different pages then within templates.

And if this box for example can be linked to a specific contact from the customer you can also let multiple people sign contracts if needed.

Particular for contracts this will be a great addition
