Transfer graphics handle between methods in Level-2 MATLAB S-Function

In the Start method of a Level-2 MATLAB S-Function I create a graphics object e.g. a surf. In the Update method I want to manipulate the object e.g. add an offset to its ZData. How can the Update method access the object created in the Start method? I tried to (mis)use the Dwork vector to transfer the graphics handle of the surf from Start to Update, but obviously Dwork does not accept graphics handles any more (since they became objects in 2011).
I know that I can use global variables (bad style) or findobj (slow) in the Update method to access the surf. Is there a better way?
