Please let us invite atleast one friend to a practice tool

I would like to be able to add one friend to the practice tool because when practicing ADC i would like to play with one of my friends playing as a real support because a ally dummy doesn't help. I would also like to be able to 1v1 a friend in the practice tool because it's a great way to practice with even match ups because in actual customs you have to wait for gold. Also the low cool downs would be ultra fun so please riot consider this one. I have asked everyone I know and they all said this would be a great idea. Even one of my friends who doesn't like the game said he would play league everyday if there was something like this that you could do.
