How can I hide dynamically added images in adobe sign template for signer 1?

Hi Community, 

Scenario is like that we have to send agreement for signature to our partners. We want to get it signed by our all 2000 Partners individually and then want to to autopopulate our company owner signature in signed agreement and then finally store it some location.

We dont want to send all 2000 signed agreement to our company owner for further signature, so we want to autopopulate owner's signature after partner signed and then store the signed agreement.

I could think of 2 options:

1) Either autupopulate owner's signature somehow after partner signed it. (NOt sure if we can achieve this)

2) Add Image of Owner's Signature while creating template and hide this image when partner sign it (partner will be only signer this time), but once final agreement is signed then everyone can see owner's signature image
