display order of connections

Is there a way to control the order in which connections are displayed ?

I’ve got a Articles => Books connection so that in each article I can quote a number of books. I want to display the quoted books in the footnotes of the article.

Currently, if I create say three books connections and then display them at the bottom of my article, I will get them in reverse order. Can I change that ?

Yes, there is a way to do this, since version 0.8:
