I tend to create a bitbake recipe to build my kernel and put it in an 
overlay, otherwise known as a collection[1] and setting the 
"DEFAULT_PREFERENCE"[2] to a large positive number to cause the build to 
prefer that kernel. That way it's building your kernel, but it's not yet 
in the org.openembedded.dev branch.
