Suggestion for the app

Hi! Just wondering why there isn’t an option to see previous meter readings submitted on the app? I’ve been doing it monthly for both electricity and gas around the same day so as I can the difference in usage from month to month however I’m still having to log in and view each statement and then work it out.
In hindsight yes I should probably keep my own records but I’d have thought something as simple as this would be displayed on the app where you submit readings?
Just a suggestion maybe?
