Is it possible to script (python) the creation of hda's Event handler?

For example (manually):
HDA –> Edit Operator Type Properties –> Event Handler = On Created

node = kwargs
print ‘CREATED’, node


Pipeline wise, I would need to automate that operation, I need to be able to ‘insert’ various Event Handler, everytime an artist creates a hda, via programmation.

Thanks,
Jonathan

Why not just install a standard event handler that reads an external file for commands? Then you can write to the external file and when the event handler activates it will process commands by reading that file?
