Allow user when viewing daily history in the phone application to toggle on/off the use of rain check for that date. The rainfall total chosen would also be reflected in weekly/monthly/yearly/all-time totals.
Reason: At least here in the northeast USA there have been a lot of extremely heavy, very localized thunderstorms. As station density in some areas may be low, a high reading cay be erroneously reduced a significant amount by the rain check feature. Allow users to toggle the use of rain check on any date when they believe the original reported amount is more accurate.
