Is it possible in SimEvents to define entity attributes using a MATLAB script?

Is it possible in SimEvents to define entity attributes using a MATLAB script?

I know how to define attributes manually in the Entity type tab of the Entity Generator block. I also know how to write MATLAB code in the Event actions tab to change the value of previously defined attribute. I want to use a MATLAB script to define the attributes so that I can skip the manual process of defining attributes and setting their initial values each time I use a new Entity Generator block.

Thank you.

I see several ways to achieve this.

1. You could store your Entity Generator block with the required Enty Type definition in a Simulink library. So each time you pick the block from the library, it is already configured as expected.

2. With a script, you could find all existing Entity Generator blocks in your current model and modify all Entity Type definitions:

blocks = string(find_system(bdroot, "BlockType", "EntityGenerator"));
for idx = 1:numel(blocks)
    set_param(blocks(idx), ...
        "EntityType", "Structured", ...
        "AttributeName", "data1|data2|data3", ...
        "AttributeInitialValue", "1|2|3");
end

3. You could use a Bus object to store the Entity type. However it doesn't allow to define a non-zero initial value, and you still have to use an event action to set the initial value (can also be done by script though).
