Main condition not =

I have a scenario where I need a condition that's not an equality test. How to achieve that?

My workaround was to add a new property called TRUE that always returns TRUE. Then, in my condition, I set the main property to TRUE with value = 1 (to guarantee that this test will pass), then I put the actual condition I need in the additional conditions. It works, but it's ugly. Is there a better way?
