I am still amazed by the amount of neat tips, tricks and new (or sometimes really old) things I am still learning every day about XAF and XPO only by browsing the daily support tickets.
This time I stumbled upon a couple tickets:
And

Those ones made me revisit the docs about Free Joins in XPO and honestly I don’t know why I haven’t been using this more often because it is a beauty.

A few days back someone in our facebook group had the same exactly question and then this article was born.
