Allow user to press the return key within Guided Write box

I give pretty detailed instructions in the “Tell Sudowrite what should come next” box. Most of the time I separate sections within that space with the return key, BUT I forget to depress the shift key, it starts Guided Write with whatever I have entered so far and N end up with unusable stuff and lost credits. Could you make it just like the Comment box where one can press the return while writing with the box and the click this?
