Keys for Cooldown Pings

I wanted to suggest adding an option for cooldown pings via keybinding. For whatever reason, whenever I try to ping my cooldowns, most of the time I instead send an assistance or ! ping where my hud area should be. In order to ping my spells, I have to hover semi precisely in the top right corner for a couple of seconds and lightly but swiftly click. It happens enough to be a big pain to me, and is too inefficient to use in an ongoing team fight. I understand this is probably a more small and personal problem, but I think the addition would have a further reaching benefit. There is an option to quick-ping Assistance or Retreat, so it'd be nice to maybe have Ctrl/Alt Q/W/E/R 1+ (or whatever custom keybinds) to ping my abilities/items/sums as well. It would also prevent me from having to move my mouse away to do it, so that'd be pretty neato, too! Thanks!
