Showing just Moviesets who contains 2 or more Movies in "Sets"

Hello

Is there a Way XBMC can show just Moviesets who contains two or More Movies?

if i scrape my Movies the scraper set automatically the "Set"-Tag. Thats cool, but if i didnt got other Movies from that Set in my Libary it shows a Singel Movie in the "Set" category. What i like to Fix.

Is there a way how i can Fix this via Skinning or Script?
Something Like: "Set.Contains.files>2" or something?

try to do it with a Smartplaylist, but there arn't the Options that i would need.

thanks in advance.
