Currently, if you set a ITAM Watch event on a field, it will be set on field changes occurring after the event is set. For example you set a create a Watch event today to let you know when a PC has been in the status of "Out on Loan" for 30 days. That watch event will not work on any PC whose status was set prior to today. It will only be set on PC where status is set to "Out on Loan" after today. This leaves any existing PC excluded from the watch. It would be nice to have the option to set a watch event on a existing field value.
