I am trying to automate some processes and programatically create a model that contains CAN Pack and Unpack blocks.

When I parametrize the mask parameters in the script, the output is as attached in the image (Message Name and dbc appear correctly, is there a way to -

Emulate mask button press 'OK' or 'Apply' so the input ports are generated without human intervention? OR
Pass the mask params to underlying S-func so it updates the block?

mdlname = 'Trial_VCCU';
new_system(mdlname);
open_system(mdlname);
x = 100;
y = 100;
    
msgname = 'VCVCCU_ChargeToVehicle';
file = 'C:\repos\VECU IO\EV_CAN.dbc';
canmsglib = 'canmsglib/';
unpack = [canmsglib 'CAN Unpack'];
pack = [canmsglib 'CAN Pack'];
msgpack_hndle = add_block(pack, [mdlname '/' msgname '_Pack']);
set_param(msgpack_hndle, 'Position',[x, y, x+1000, y+600],...
    'DataFormat', 'CANdb specified signals', 'CANdbFile', file, 'MsgList', msgname);
