Hello Todd,
I was looking around for an article from the Resource Center and I found the two below.
https://help.mypurecloud.com/articles/edit-contacts-in-a-contact-list/
https://help.mypurecloud.com/articles/download-contact-list-records/
However I'm not sure if they will directly help you accomplish what you're looking for. I'm not aware of any to implement versioning on your contact lists. You ma need to submit this as a new Idea in the Product Ideas Lab.
To Access the Product Ideas Lab and add your idea:
- Sign in to the Genesys Knowledge Network.
- On the Product Ideas Lab section, click Browse and Submit Ideas.
- From the Product Ideas Lab, click Add a Product Idea.
