One thing that is possible but rarely done is when the ad is created, it is possible to edit the title of that ad. By default it will say (prem/LE) but that can be corrected to only read the model you want.
This only helps in terms of seeing what model is actually for sale - which i think is interesting if you are on the hunt for one or the other. The ad is still linked to the prem/LE game for sales history purposes.
