Alarm Status Table - Last In Time

Hi,
I am looking to add a column that displays the 'last in time' on an Alarm Status Table. Anyone have any suggestions?

Last in time - The first instance of an alarm from a source that has NOT been acknowledged. Example: An alarm is active at 1:00, then cleared, then active again at 1:05, but never acknowledged. I would want the 'last in time' to display on the new instance as 1:00.

'Adding a column' to the AST in Vision or Perspective is more or less not going to happen either way, but let's start with: are you using Vision, or Perspective?

Sorry, forget to mention I am using Perspective.

I am assuming I will add a column under columnsAssociated on the AST props. Maybe a better way to word my question is... 'What is the best way to get/store the last in time in a custom alarm parameter?'
