Sorry for delay in my response, I must have missed the notification that you responded.
iXp is not as fine grained as the WCC/EEM sendevent restrictions (Thanks for pointing that out Steve). If the filter for JOBCONTROL matches a job it will display the entire JobControl popup menu selection - there is no further fine grained control at this time.
If I am still not understanding your question, perhaps a screenshot or two would get me on the right page.
