Heat Tracking Clip for Quintessential FightTech

I've just started playing the Quintessential FightTech rules and I wanted to use something other than a pen to add heat during the movement and combat phases only to rub it out again in the end phase.

The idea of using a clip for marking a position on a game's data card is nothing new, and I doubt that this is new for QFT either but if there is such a beastie out there before or since the Unseeing, then I've not found it.
