Single signature document

Hi, 

I am just now testing the adobe sign service and am looking for how I can have a document signed by just one person, but then many. 

We have more than 500 staff members and each of them has to sign our new Code of Conduct digitally. So this is not a contract where two parties sign but a document that is signed by only one person each time. In the application I see that I can do that but not in a bulk, I have to make up a new document for each email address (signee). Is there a way how I can automate this to more email addresses with each of them being a single signee to their very own document (without another party signing as well)? 

Thanks for your help!
