Custom Quartz Filter In Preview Not Showing Up

In Snow Leopard, I could create a custom ColorSync profile to reduce PDF size (but not with quite as a dramatic drop in quality as the default PDF Reduce File Size) and it would show up in Preview as an option.

Now, in Lion, I still have the profiles, but they do not show up in Preview as a choice. I also cannot edit the default Reduce File Size profile in ColorSync as it is perma-locked.
