Can I "turn off" the essentials to not have double entries?

Hey all, I bought the D&D DM Starter Bundle to use in my games. Now what bothers me is that I now have redundand information in my compendium in the games. For example, when I go to "races" I see 'Dwarf (PHB)' and 'Dwarf (EK)'. Both is the same, as the EK is a bit like the Player Handbook Light IMHO. Is there a way to turn off the EK to have less clutter? These double entries come up at various places, like spell lists, rules, backgrounds and so on... I'm currently not really sure how useful the EK actually is to me, when I have the PHB.... (not complaining though, just wondering). Any ideas on this?

This has been brought up in the suggestions forums several times, and then dies for lack of votes. I too, would like this. It makes it cluttered to have Ravnica material show up when you are running an Acquisitions Inc. game. If you want to make a Suggestion, you'll have my vote. Maybe you can succeed in getting enough votes where I and others have failed. :)

Well, I doubt that I have more influence (or luck) than you :( But thanks for the answer, for the moment it looks like I just have to live with it :(
