Where is CNAME?

I'm trying to take advantage of a CDN service, but I cannot locate the CNAME record when going to: Services -> DNS Domain
or is there another way of doing it with virtualmin?

Here is what I need to do:

replace this: friendsforcash.com. IN CNAME 66.135.33.117:80

with:

friendsforcash.com. IN CNAME wp-7f691d0000000000.id.velocix.com
