Subscription to receiving a message associated with any token

[frabor1]

I wonder if there is a way to subscribe to a message regardless of the communication channel.
In my application I have several ViewModels that send the SelectedItemMessage, each specifying a different token; however in the viewmodel that manages the menu I need to intercept all of them, regardless of the token.
Is it possible to do this without subscribing to receive the message for each token?
Thanks in advance
