Crediting a Filmmaking Duo to their individual credits

Hello, my brother and I are a filmmaking duo and we have a credit as “The Matarrese Bros” for a project. We wanted to go fire out the best way to merge that credit with our individual credit listing? Do we each try a name merge between our individual credits listing and the new duo listing? Or is there a way to merge the duo crediting listing with our individual listings simultaneously?  

And is there a way to automatically have our duo listing (The Matarrese) added to our individual credit listing? Thanks!
