it might be able to be done, but not currently by referencing the name of the spell - you need to reference the cast button as a number because of the repeating section. the first spell in the list is tagged with_0, and counts up from there (the second spell in the list is _1, and so on.) I couldn't tell you how to get the exact names you'll need, but your macro, if it is possible at all, will need to point directly to the right section, and be named appropriately as a token action. (it will need to specifically reference the right spell level the table is stored in, and then count down to the right spell.) I remember doing some experimenting with this, and decided it was simpler to simply require my players to pull the character sheet up and then click the cast spell button.
