Using Willpower to temporarily buy off power flaws?

[Zombie Haiku]

Hi all,

Just getting into a Cold War Wild Talents game after a year long hiatus from Progenitor and I have a question?

I seem to remember something about being able to temporarily ignore a power flaw by spending willpower but I can seem to find where I've seen it or if I'm making it up.

Does anyone know if this is a thing and if not, how would you go about it. Player wants a slow acting power (Delayed Effect) that can be pushed to speed it up.

Thanks in advance.
