Mea culpa -- you are, of course, quite right. I shouldn't have said "all"! There may be other programs where things are even more limited. UA actually has some of the most liberal rule sets out there, when you factor in the fact that *A partners can be mixed in without restriction (compare, e.g., to AS, which has a very nice partner list but only allows one partner on an award).
