Workdrive Custom URL CNAME Specifics

Workdrive Custom URL CNAME Specifics

I'm having trouble mapping my custom domain on Workdrive.  If I'm reading the instructions correctly, I'm supposed to add two CNAME records, one with the name "workdrive" and the other with the name "WorkDrive-[uniqueID]."

My question is whether my domain should be in the record name so:
* workdrive.domainname.com
* WorkDrive-[uniqueID].domainname.com
