Keypads and other macros allowed in LCS?

Whenever I play league of legends, I like to start everygame I play with saying that I don't play with a keyboard. The sound of my team calling gg 2 mins in never gets old. This is true however. I use a Razer brand keypad. It supports my wrist more than a traditional keyboard will ever do. I was wondering if things of this sort will ever be allowed into LCS if it isn't already.

The thought of someone who has been playing with a keypad and reaching a point to where they can enter LCS and being met with a resounding no would be terrible. One reason I could find that it would require the computer to have Razer Synapse installed so the keys function properly.

Any information on this would be greatly appreciated!
