Module function

Hello! Brand new member here. I’m confused as to which purchase level includes the modules function. I’m interested in using modules to define groups of firing positions, to perhaps make it easier to do simultaneous multiple launches. Or is there an easier way to accomplish this function? I have a basement miniature model theme park, inspired by Disney parks, and hope to display an FWSIM show on a large monitor behind my castle. Thanks and cheers!
