Is there a timeout for approving/declining transactions? I'd be interested in setting up a sort of 2FA for large/over budget transactions where I'd have to manually approve it before it goes through. e.g. "You've already spent over your monthly Amazon budget by X amount, are you sure you want to make this $200 purchase?"
