Recurring bills don't always fit into neat timeframes like "monthly" or "semiannually". For example I pay my property taxes twice a year in May and August. The result is that I have to set up two separate recurring items, one for each of those months. Which is fine.
The rules that get set up to apply payments to those items however, look like carbon copies of each other. Both are being paid from the same account, both have the same merchant, both have the same amount and both are due on the same day of the month. What differs is what month they are due in.
I assume this means the first rule will always capture the payment and it will always be trying to apply it to the next May instance so the August instance will never get triggered. We need to be able to say this rule only triggers if the transaction happens in May (or August) instead of just saying what day of the month it is expected on.
