There is no way to filter incoming transmission with the VON Component.

For example, mods should be able to edit or stop incoming transmissions from reaching the player. Currently multiple mods have a spectator feature and in my instance I attach the spectator entity to the camera so the player can hear comms on the ground. Right now the spectators VON is disabled so the spectator can't talk to active players, I could simply fix this if we had the ability to filter incoming VON transmissions like we can with outgoing.
