Hello, In V3 I can set up a custom CAN message and activate the CAN bus stream for a vehicle. Is this part of a new feature? In V2 this was not possible, I had to switch the can bus stream for the vehicle to the custom stream. ![Screenshot 2024-05-19 105917](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/1X/c687341475d60eacb3626e35c90d22ca5e9eaff9.png) It would be nice if we could use it that way. ---

As Greg wrote. In V2 you can only send, in V3 you can send and receive.
