Replace "None" date shortcut with "Next Month" (or other)

I use the date shortcuts in the Date picker frequently. I use "Today", "Tomorrow" and "Next Week" a lot, but find the "None" button to be not that useful. More than that, I feel it is redundant since you can just click the "x" in the date time box to remove a date. I feel that button could be replaced with a different date shortcut, with my suggestion being to be Next Month.
