Special Hero Buttons

I have been wondering about this one for a long time:

Is it possible to make a button that opens a whole new set of buttons on a hero, kind of like the level up skill button, which opens a new set of buttons that are skills to learn. I need this to make a spell menu that is uncluttered and has more space, meaning more spells.

Any help will be greatly appreciated, Thanks!

If I understand you correctly you can do what you want useing the spell book ability that is found on the spell book item. It allowes up to 11 extra spells

Thanks, but I just figured it out right after the post, so I let it die :D . Thanks anyways though!
