Feature Request: YNAB should warn when monthly spending is unsustainable, right?

I've run into a situation that I was concerned about from the start. If you start YNAB with a lump sum of cash available, you create all of your categories, goals, etc. It then is very easy to fund all of the categories. Then, you think things are going well. Spend, Fund, Spend, Fund every month.

But, without looking at reports (which can be hard to interpret depending on certain money flows), after much time, there will be a month where you realize that you can't fund the entire month up front which is an aha! moment indicating you are spending more than you can afford.

I wish there a way to definitively know this sooner so you can adjust monthly targets down, eliminate categories etc. The result is that you no longer have a chance to adjust while you had the excess funds and rather have to adjust too late in the game.

Does that sound familiar or am I just missing something fundamental here with how to use YNAB reporting, etc.
