Is there a sticky somewhere on flyertalk with a tutorial on using the ita matrix software, particularly for advanced use-cases? I use it often to plan trips but cannot seem to figure out how to only allow or disallow multiple fare codes on a single carrier. For example, SFO-AMS r/t on KLM only for fare codes Y,B,M; or, SFO-AMS r/t main cabin excluding R,G,V,X.

Thanks in advance!
