That's absolutely correct. Right now, you can take the output from the Network Config Generator and then paste it into NCM for execution.
As noted in If you're curious as to what we're working on..., we're working on a version of NCM that will give you the ability to leverage Config Change Templates directly from within NCM. Config Change Templates created by the community using the free tool will work in NCM and vice-versa.
I've included a sneak preview of what this will look like in NCM
