ditto list with GROUP BY pagetitle

I’m trying to work out if it’s possible to get my ditto list to GROUP BY pagetitle

I have resources that have the same pagetitle but I only want to show one. Does anyone know a way to do this in ditto?

many thanks

try this extender:

thanks Bruno, I’ll give that a shot
