How to make Spellbook not unselect when casting a spell?

[Maridot]

I'm trying to make a hero skill system based on the spellbook item ability, however whenever I cast a spell with the unit it goes out of the spellbook into the heros root abilities.

How can I make it so that it doesn't quit the Spellbook upon cast?

don't use shared cooldown between main and hided spellbooks ,that causes it AFAIK.

How do I remove it?

there should be a line in object editor for the spell book that reads "share ability cooldowns" or stng similar
