I had the same frustration and solved it this way...
within the cookie window:select your optout cookies and add to whitelist (there are instructions for this in Cookie's help window if needed). uncheck boxes for the 1,000,000 cookies sort by favorites: click the favorites column header aka and you'll see checked+unchecked boxes toggle up/down as you click.
henceforth Cookie will remove all non-favorites as usual but ignore the whitelisted cookies!
two things: first, this is not an ideal situation but solves your problem as described.
second (and most important!!) you've probably had the opt-out domains favorited for a while- it's likely that those folders have numerous non opt-out cookies within; you REALLY don't want to whitelist those
If you have questions as to how to discern between opt-out cookies and the other cookies, reply and I'll attempt to explain. Many have "opt" or "0-cookie" in their name. If you're wondering why a domain you opted out of is still adding cookies, cringe a little and read everything below my signature.
Alright, that's my mostly imperfect "help". Cookie is an exceptional application and can be tamed enough for your situation. Many thanks to Russell- you've created something splendid !

[u]Okay guys and gals- here's some further info for you on tracking:[/u]
I revamped my privacy setup (and deleted all optout cookies) after reading a lengthy publication on identity tracking a few months ago. I think it was MIT...or a group in Germany...oi! I'll track it down if anyone wants to read it.
Basically, the more clutter you have attached to your browser the more identifiable you are. The optouts are numerous, hence "trackable" (your plug-ins, extensions, and many other bits of data contribute substantially too).
You can avoid half the mess with a combination of Cookie and a few browser extensions; Little Snitch can be a great add-on too.
