Ability to block merchants

I thought it might be cool to be able to block merchants from taking money from your account if you’ve previously used them before. For example with subscriptions that don’t use direct debit, you should be able to cancel payment for the subscription via the Monzo app in case for any reason you are unable to do so quickly with the merchant. Recommending this after a personal experience, wondering if others might like this? Opinions please
