I use the custom item sets a lot, how do I keep them after the open beta client kicks in?

I use often use different builds from those recommended or those from things like championify. It really allows me to gain a lot of time (you like rick clicking a legendary offensive item in your recommended section and then start buying some tanky-ish item too, right?

I kinda feel like you're saying a plain out no to non traditional builds... Here are a few examples of the ones I use the most: http://i.imgur.com/vsJuv4O.png

I also use the item sets to have immediate advantage the moment i die (anyone seen siv's video, where he uses an item set full of mejai's, so that if he kills an enemy with ignite post-mortem, he gets extra stacks?) when I play brand (there could be others, like cassiopea...) rylai's is a core item, and if I die with, say, and ultimate that will proc 3 stacks a few times, i'm happy to be able to slow them in order to let my team escape or chase them down. This could actually win a game: http://i.imgur.com/d8WCbfH.png

Please, I don't mind you removing it from the client, but I really need the item sets to be available, maybe in the game files? Or officially recognize a third party programm that allows for personalized item sets
