See who deposited and withdrew money in a joint account pot

I’ve just been looking at a savings pot in the joint account I share with my partner, and I’ve realised that there is currently no way, other than searching through the full history to see who deposited and withdrew what from a pot in a joint account. It would be good to have even just the little picture next to the deposit, or even a breakdown to say what each person withdrew and deposited

Any reason? I don’t really see this as being in the general vein of what a Joint Account is for? Surely it’s joint so it shouldn’t matter who withdrew it etc? If you’re unsure about a transaction just ask the other person?
