Integrating file paths/extensions into CCleaner

First I would like to say THANKS to everbody who mods here. I have been lurking for quite some time and the only reason is that the mods do such a good job that i dont need to bother with questions. but I finally have one. here it is: I use CCleaner in conjuction with a batch script that i wrote. i know that you can intergrate new programs into cleaner but is it possible to intergrate just simple file paths or certain file extension to delete. also if it would be easier is there a way i can integrate my script into cleaner. Thanks in advance for any help or advice that can be offered
