Possible to edit (batch define) hazlrules w/external editor?

I recently purchased Hazel and am excited about the prospect of using it to clean up after a couple of years of lapsed discipline in file management/organization. Before the lapse I maintained a fairly elaborate schema of directories and associated files, and I'd like to use Hazel to fold the accumulated clutter of the last few years into that schema. However I'm hoping to avoid the chore of manually specifying each hazelrule required to accomplish that in the conventional way, using the Hazel preference pane.
Is there any way to directly edit the /application support/.hazelrule, or some other efficient method of defining a large number of hazelrules?
Thanks in advance!
