<p>Hi Josh,</p>
<p>No I didn't! Although I don't know if that means it isn't
possible, I didn't spend too much time looking into it because I
found an alternate way for me to do what I needed to do. I feel
like it should exist, although I also don't think alphas are
studied too commonly using Gate.<br>
