You should at least get a yellow prompt box on the TP which asks the user if they want to resume from that line. This may be a production check setting under Setup - Prog Select.
Regardless, this doesn't really help as it's just another step they can preform. You should be able to prevent access to the program with the password option. Alternatively, you could send a signal to the PLC when the TP is enabled and track it that way.
