Steve please try and report back... Appreciate it.
I'm re-thinking this a bit, Donny do you want STS 2 to open with Variation 1 or STS open to let's say STS 3 with variation 1? If that's the case then I don't believe it can be done. After re-reading your post a couple more times it finally sunk in my small aging brain
P.S. Just tried it on my Pa3x, does not work on the 3x either.
