Add Instance description to an Alarm UDT

I created a UDT to take a Tag and assigned numerous members to the tag. I set an alarm to trigger when the InAlarm tag is set to high. I want to display on the Alarm (History, summary & Alarms) displays to display the description and not the instance. But I have not found a way yet.
Here is my UDT


and the Alarm setup

I need to be able to enter the desc in my instance tag (not an OPC)
thanks
