NCV and SPLITNCV

I have multiple datasets that I am currently using NCV to create a graph for. But the problem that I am running into is that I would like to have say 2 of the datasets go to test.success.rrd and the other 3 datasets goto test.stream.rrd. I can't seem to be able to do this with NCV but searching on the net I found that someone created a patch that included an option for SPLITNCV_column-name. But looking in my version of hobbit in hobbitd/rrd/do_ncv.c file it doesn't have the parameters for the SPLITNCV option. Is there a different way that got incorporated into hobbit or can someone show me how to use SPLITNCV.
