Using multiple charges of a skill accidentally

It’s too easy to accidentally use multiple charges of a skill in this game. I’ve been having issues with Shadow Rend. I gave it an extra charge with the “Flourish” node. If you hold down the key just a tad too long it’ll use both charges in succession. It’s especially easy to do with this skill cause there’s a short delay before it happens, causing the player to naturally hold down the key longer. Can you please give us a setting in the options to prevent holding down of the key from repeatedly casting charge skills? That way, only discreet button presses will work. Only for charge skills. Thank you!
