To all -
I am aware that an admin can add alert custom properties to the severity section on the alert properties page but is there a way to customize the categories for the Severity of Alert pull down options? I've seen a couple of posts on Thwack but i have yet to find a definitive answer as to if it's possible without seriously modifying SW.
In short no, there is no ability to modify the available Alert Severity values. There are some feature requests you may be interested in voting on
As possible workarounds we have seen some clever use of custom SWQL CASE statements to provide custom mapping of custom properties to a user defined alert severity
