Hello @fishtahoe (Todd) 
, welcome to DevKinsta community!
This feature (Cloning existing DevKinsta sites) has still been being worked on by our internal developers, and they have planned to implement it in the next release of DevKinsta (hopefully in the next few months) 
but we can’t tell the ETA for that.
Once that feature is available in the new DevKinsta version, we will surely post it our our forum thread 
Cheers,
Agus
