If you mean by UL to lower rows in the UL there have been none that I have seen yet on this thread. You'd have to assume that is what they are working on now and it may be muddled by the relocation of the UL end zoners.
I'm interested in the highest rows of Upper Levelers that moved to the LL. Just based on memory I think Row 11 or 12 or so. Anyone moved from higher up in the UL to the lower bowl?
