Hmm.. odd I do it that way all the time for obz. Well try the script method EldritchCellar mentioned. It should be somewhere in your Scripts menu (Can't tell you exactly where, because I move all that type of thing into catagorized folders for myself). Just be aware doing that will increase your runtime size / disk usage as it it decompressing all those compressed files.

Consider me insane if you wish, but is your reality any better?
