Not that I know of, but here's a way to externally supply the pairs of
objects to fire on:

rule
when
    $list1 : ArrayList()
    $list2 : ArrayList()
    Pair(first==$list1, second==$list2)
then

If you find yourself reasoning about the order and timing of insertion
events, you may want to look into drools fusion instead.
