Passive leveling hero abilities

[shocker]

I created an leveling aura for a hero. Which all works but when u get the ability, you need to click on it to turn the aura on. How do i make it so when u spend ability points to buy the aura, it auto turns on?

The way I would probably do it is I'd have the Aura behaviors added on the unit that has this ability in the data editor, but I would have the behaviors use a Requirement to check when your ability reaches the level assosciated with each aura behavior. This way you should have an aura that won't even need to be turned on, and will be a true passive.
