Not for beta 3. It's on the list, but it will need a little research first. Calculating this is a little more complicated, and there are some gotchas, and I since all of the formula variables have to be calculated several times per second to be made available to conditions formulas, I want to make sure it won't introduce any unnecessary lag. Now that I believe I have squashed the weird high CPU usage bug, it's more likely it can be added, but like I said, gotta do a little research first.
