Is there a smart way to present the marriages of two brothers with two sisters of a different family when the elder brother marries the elder sister and the younger brother marries the younger sister without disrupting the left --> right arrangement of ages amongs siblings.
I think it reduces to: is there a way to cross trees and in particular union objects?
I appreciate there is a tutorial on "How to marry two brothers with two sisters from a different family" but in that example the younger sister marries the elder brother and the elder brother marries the younger sister.
Thanks in advance for any input.
