Apologies if this has already been requested — I know it’s probably “one of those” posts.
When you recategorise a card payment, Monzo asks if you want to apply that category to all past payments from the same merchant, which is great, but it only works for card payments.
I recently opened an account, made two Amazon payments, and had to change both to Shopping manually. It’d be better if this worked more generally — tap a transaction, change its category, and get asked “apply to this 1 payment, or all matching payments?” So if you had 79 transactions from the same merchant sitting in the wrong category, you could fix them all in one go.
