You can also write "See explanation" on the side somewhere. Then in the explanation explain that you are applying for I-212 prior to departure and will be filing I-601A after approval of this form.

Now note one thing: I-212 is a strictly discretionary benefit meaning that it can be approved for any reason, including no reason at all.

Here's a good read on it:

For all intends and purposes you can argue extreme hardship to a relative and other factors with your I-212, and then recycle the same argument for I-601A.
