I wish there was a

I wish there was a way of creating your own security levels in ie. I have basically turned flash to prompt in my security settings now as I am fed up of getting those annoying banners. However, one of my regular visits uses flash for an advert, so everytime i load the page up it loads flash. What I want is a zone where I can set download flash stuff to NO but still allow the posting of forms…Anyone got ideas of how to do this? The sites don’t really fit in any of the standard ie security zones.
