Curves adjustment in NConvert?

[beornlake]

First off, I just found XnConvert and NConvert today and these are wonderful tools! If I can get them to do what I need, I'll absolutely be buying a business license!

So, my question:
Is it possible to do Curves adjustments in NConvert? I built a script in XnConvert GUI where one of the crucial steps is a Curves adjustment. When I exported the Script for NConvert, though, all of the steps except the Curves adjustment were in there, and I can't seem to find any reference to Curves in the Help page. It looks like this feature isn't implemented, but maybe I'm missing something?
