Hi all, I use CC in Rfactor2

When I use old 70's F1 cars, as at those times, there were no radio messages to the driver, so I do not want to receive messages from CC ... but I still need to have and receive the CC messages (only) when there is an opponent on my right/left.

In other words I would like to have CC speaking to me only if/when it has to communicate "car left"/"car right"/"still there"/"clear" and no other messages ... how to do that in CC properties ?

A great thank you for your help
