Two Ring sirens on one system?

Is is possible to add two Ring sirens to one alarm system.Many traditional alarm systems have a siren/bell box on both the front and the rear of the house.In most cases the rear doesnt sound. it just lights up. Its a dummy box. But linked to the main system in order to turn the light on/off and sometimes flash if soundingI suppose i could buy a Ring siren and rig up an LED inside on a timer. But that’s a bit of a faff.Would be easier to just by another Ring Siren and disable the sounder
