How to achieve both approval and create a primary Forecast automatically about Budget?

My customer want to applove budget and create a primary Forecast automatically.

But my understanding is that if approval is enabled we can't create a primary Forecast automatically because it is not appeared "Create Baseline" in Action button.

I think we have to enable check box "Create Primary Forecast Upon Baseline" like the following screen shot and we can create a primary Forecast automatically if we don't use apploval becase we can show this pop-up window.

Is my thinking correct?

Please let me know.
