is it possible to have paladin aura automated on surrounding characters?

Hi guys i would like some help in setting up a paladin aura.  what i would like to happen if possible. is to setup an on off switch that my paladin can use on his character sheet for his aura. and an instance of if characters come into contact within his radius aura the aura automatically applies the benefit and save and when they leave the area within roll 20 they loose it. and its controllable by the player. is this possible?

it works fine. it still needs a few tweaks.&nbsp;
