Auto-Use Quickslot Momento?

[NeuroticPixels]

I may have dreamt this... But I could have sworn I saw an addon that offered the ability to keep a quickslotted momento used on each cooldown refresh.

I've tried searching a little with no luck in finding what I'm looking for.

I'm a big fan of the momento "Almalexia's Enchanted Lantern" (great for dark areas) and it would be great to have an addon that automatically used that momento from my quickslots after each cooldown.
Of course, it would need to check for crouching/stealthing so that it didn't ruin my sneaky/thieving times.

Is there an addon that offers this already? Or anyone interested in creating a new addon for this?
