can you use Zulu to create default alarms

Do you have to create the alarms in ical or can you do this in zulu?
If not in zulu, what happens if your ical is set to default with an alarm, would this then create that alarm on every zulu entry. I am really preferring a script or filter step so the user can select an alert or no alert check box when using FP or FPGO.
