How can I get the port number of a StateFlow input given it's handle programatically?

I have the handle of a StateFlow input from a previous find result. I'm trying to get the port number for that StateFlow input. I've been using the sf('get',<handle num>,<field name>) command for other fields like 'data.name', 'data.scope', etc. but can't see where I can get the port number. Can anyone help me with this?

chart = find(sfroot, '-isa', 'Stateflow.Chart', 'Name', 'YourChartName');
inputs = chart.find('-isa', 'Stateflow.Data', '-and', 'Scope', 'Input');
for i = 1:numel(inputs)
fprintf('Port %d: %s\n', inputs(i).Port, inputs(i).Name);
end

It sounds like you are working with Stateflow.Data objects, where you have the ID property and want to find the Port property. In that case, you can do this:
>> x = find(sfgco,Id=301);
>> x.Port

You can use sfroot instead of sfgco. That will look at all the Stateflow charts you have loaded.
>> x = find(sfroot,Id=301);
