how do I unblock specific ads with Kerio?

Hi

I use the latest Kerio 4.1.2

I see the Ad block option that has the built in filters, and I also see the site exceptions tab.

What I want to do is not block ads.workopolis.com (it's pretty seeing all the company logos), but not affect anything else.

If I add a filter to the site exceptions it doesn't seem to have an effect on the ad blocking, and I don't want to disable the built in ads.* blocker for obvious reasons.

Any ideas?

thx, Bodi
