Modifying Read Only ID of CAN message

I'm using a network of multiple sensors that I want to configure over CAN. Each Sensor has an ID from 0-7.

I currently use a CAN-database to create the Config-message. The default config message identifier is 0x200. The identifier gets changed based on the sensor I want to configure like this:

message-ID = 0x200 + sensorID*0x10

So the config message for sensor 0 has ID 0x200, sensor 1 0x210, sensor 2 0x220 and so on. The same is true for all other messages that can be sent.

The easiest solution for me would be to modify the message-ID from the default message (ID 0x200) like I'm already doing it with the signals:

msgRadarCfg = canMessage(dbc,'RadarCfg');
msgRadarCfg.Signals.RadarCfg_SensorID = sensorID;

Message.ID however is read-only, so this doesn't work:

msgRadarCfg.ID = msgRadarCfg.ID + sensorID*16;

Is there another way to change the message ID without me either modifying the dbc-file to include all messages for all sensor-IDs or building the messages "by hand"?
