How do you programmatically invoke model callbacks?

For organizational purposes, I've defined my Simulink model's PreLoad callback expressions in the model explorer's callback pane directly, and NOT broken them out into a separate script file (so that all the necessary info is contained in the .mdl file). I'd also like to re-invoke the expressions IF the workspace has been cleared between the time the model was opened and the time it was run. So, I'd love a way to generically run the contents of the PreLoad pane without copying all of it into the InitFcn pane. Does anyone know of a way to programmatically run a model's callback function with a generic command?
I figured there would be a command similar to setting a model's simulation command to 'start', but I can't find a corresponding parameter for a model's callback.

Kind of a hack, but this should work:
>> eval(get_param(bdroot, 'PreLoadFcn'))

I'm not too worried about a method being a 'hack', as long as it's a generic, reusable 'hack'. This works perfectly, thank you.
