Is it possible to access local data from a chart in a simulink state?

I use a Mealy Chart and want to store a value within the chart for later use. I've set the data type to 'local data'. Now I want to access the data in a Simulink State but I've no idea, which Simulink block I have to use.

I can't just use a Data Store Memory because the Machine Type Mealy disallows it.

Edit: My current workaround is, to write the data to an output and pass it in to an input because I can acces inports and outports from a simulink state. To get it working I still have to use a delay between the output und input. It works, but it's not pretty and I have to add some stuff outside the chart.
