Here’s a short video of the update in action:

1. In theory, payday for me is the 11th and the 26th. Unfortunately I get late paychecks often. So my 26th paycheck may end up coming on the 1st or 2nd of the following month. My budget plan calls for me to allocate that paycheck to the month it was in, but if I get it on the first then I could not go back in time to the previous month and allocate it.
2. I get paid on first day of each month. Generally though, since I have direct deposit, it often shows up a day or two early – especially if the 1st falls on a weekend. I don’t want to spend anything until I’ve allocated to my income to my envelopes.

So before being allowed to set the allocation date I’m sure you can see the problem with these two scenarios. Your funded and remaining amounts wouldn’t quite match up for a given month if you didn’t allocate on the right date. Now you can allocate and specify the date to be within the month you need it to be.
