Can you script L2 Mage to Power Up for L3 spell?

[K]

With boosting spells like Earth Power and the option of using gems to boost by one, you can cast spells much higher than your actual level.

For example, you are an Fire 1 mage with a Crystal Shield. On round 0 the Shield casts Power of the Spheres, and now you have Fire 2.

On round 1, you cast Pheonix power, and you are a Fire 3.

On round 2, you cast Flaming Arrows(F4) with an extra gem.

Each time you scripted a greyed out spell, but it showed up in your orders.
