They really can't. The way of seeing this in EM is that IF you are the same permission-level or greater THAN you can see through the GUI IF not then you cannot see through EM.
IF you have R/O to the system tables why do you need to see the GUI? The tables are sysjobs, sysjobschedules, sysjobsteps, sysjobservers, sysjobhistory and provide all the same information?
