Question Variable Channel 3D Properties for Positional Channels

It seems that from the documentation, that players would be restricted to the same Channel3dProperties.And that players.
I am also aware, that there is only one Positional Channel allowed at a time.

Is there no way to say give special effects for one player, where they could be heard over a much longer distance?
Example Situation: Player gets a loud speaker so people could hear them from a larger distance.
