Any Simulink block can be programmatically set using the set_param function. Look here for documentation. The catch is you need to know exactly what that parameter is called for your particular block. You can do this using the following steps:
- Interactively select that particular block in your model
- Execute the following command on the MATLAB command prompt
>> get_param(gcb,'DialogParameters') %Before executing this command, the 'CAN Pack' block was selected

DataFormat: [1x1 struct]
CANdbFile: [1x1 struct]
MsgList: [1x1 struct]
MsgName: [1x1 struct]
MsgIDType: [1x1 struct]
MsgIdentifier: [1x1 struct]
MsgLength: [1x1 struct]
SignalInfo: [1x1 struct]
NSignals: [1x1 struct]
StartBits: [1x1 struct]
SignalSizes: [1x1 struct]
ByteOrders: [1x1 struct]
DataTypes: [1x1 struct]
MultiplexTypes: [1x1 struct]
MultiplexValues: [1x1 struct]
Factors: [1x1 struct]
Offsets: [1x1 struct]
Minimums: [1x1 struct]
Maximums: [1x1 struct]
Remote: [1x1 struct]
In your case the property name is MsgName. To set this using set_param, you would use the following syntax for example:
set_param('myModel/CAN Pack','MsgName','myMessage')
Again, refer to the documentation (linked above) for the full syntax or how it applies to other parameters. Note also that, when you do this, you don't have to worry about clicking 'OK' or 'Apply'.
