The ability to change the name servers for GHL registered domains so we can take advantage of having the domains purchased/registered with in GHL but the ability to use other Name Servers for DNS management for example to use one's own Cloudflare account (whether agency or end customer's). There are use cases where we need to be able to do this and currently if the domain is registered (bought or transferred in) with GHL then the DNS management has to be done via GHL.
