You can only change custom properties.

You can only change custom properties.Ok, thanks for the tip Network_Guru, but I can only change a custom property in a Basic Alert, not an Advanced Alert, right?
Custom MIB poller values are only available in an Advanced Alert, so is it possible (how?) to change a custom property value based on a 'Custom Node Poller' trigger condition within an Advanced Alert? The 'Change Custom Property' is not include in 'Select an Action' ('Add New Action' button of the 'Trigger Actions' tab in 'Edit Advanced Alert').

You could write a script to manually change an entry in the DB & have the alert manager execute the script, but that is hardly a scalable solution.
I suggest you add this to the list in this post:
What can you do with the Basic Alerts that you CANNOT do with the Advanced Alerts in 8.5?
