Set Start of Month

I too would like the option to set a custom month ‘start’ date for stat purposes, but of course this might vary month-to-month (like where the given month ‘starts’ on a weekend, for example), but I like this idea even more - the ability to mark a credit from a particular source to be the trigger to reset the statistics.
I wonder how this could look in the app though - I guess there’s a bit of a trade-off here between functionality and keeping things straightforward for users that don’t want anything too advanced. Maybe a ‘Mark as Salary’ toggle or something similar in the feed? - In any case, this is probably something for the ‘bank’ and not a pre-pay card…
