CSV export for joint accounts - identify cardholder


I have just done a CSV export from our joint account, and I can’t see a way to identify who did a card transaction. (me or my wife). Is there a way to identify this, or could a column be added with the last 4 digits of the card or some other identifier. This would help when analysing who is spending what! Our RBS joint account has last 4 digits of the card in their CSV export.



I hope someone at Monzo takes a look at this, as lack of this information makes the exported data useless in some cases. For example, I wanted to check how much I spend on TFL tickets on average in a month but there’s no way to do distinguish my charges.
