So for ELS, I want to have some of my vehicles use the FBI siren. Is this possible? I have my regular police slots as LAPD vehicles set to the smart siren (police 1-4 slot) Then I want to set the FBI vehicles to the CHP sirens. Is this a possibility? Because with ELS even though the vehicle is in the FBI slot, It still uses the police 1-4 slot siren tones.
