Split Bill from Joint Account toggle

We use our joint account for everything and when my wife and I are out separately, bill splitting works like a charm. However, when we are out together with friends, when it comes to splitting the bill, we have to mess around with a calculator still as our share of the bill should be x2.

It would be great to see an option to tap on the ‘You’ part of the bill split so that it doubles and counts for two people rather than one.
