Variable Dice Roll in Effect

I'm looking for a way to code an effect for the Investigator's Tenacious Inspiration talent. Regular inspiration is easy, just SKILL: 1d6, but I want to make an effect that rolls two dice and drops the lower result. I can do this in dialogue with /die 2d6k1, but if I put that in an effect, it does nothing. Anyone know how to do this?

It is not supported in effects; only straight dice addition/subtraction. Any additions like this would require an extension to modify the code; and adapt to whether running in FGU or FGC.

Regards,
