[CentOS] Looking for a better way to build

I have been following the wiki on how to build a custom kernel, and it works great.

Except, I am doing ongoing work with the internals of the kernel, and it is really awkward to set up a change and then build it using the standard methodology (edit the file to change, diff it against the original to make a patch file, rebuild the whole thing).

Isn't there a way (and what is it) to play around with the kernel source files until they are in the shape I want them to be in, and THEN go through the whole build process again.

Thanks.
