Polish needed for custom item sets

Greetings Summoners, and Riot!

I play a lot of games and deviate often from the suggested items list while playing games. To help accommodate this I have taken to creating custom item sets from the client. However (the issue) creating the item sets seems to be rather cumbersome taking a lot of steps to complete a simple task, and in the end taking a lot of time to provide just a single item set. This is especially true if you are using a guide for reference.

Solution: Please rework the UX (User Experience) of this section so something a bit more streamline and that takes less clicks to complete tasks.

Mock up (old - before there was a built-in system in the client) - See attachment.

Something like this can allow users to select the champion (add a key modifier to select multiple champions) Select your category and drag and drop from a grid of items.

This will free up more time and make things easier to edit giving the players more time to play the game. Please let me know what you think.

Cheers, Stitchless
