The ability to use Alert Custom Properties within the Alert being generated by the particular Alert Rule would be helpful. Just as using other types of Custom Properties through Orion is helpful.
In my case, I am looking to have canned text for things like API Posts and Log Posts. By inserting the variable reference rather than having different versions of the text for these Actions makes Administration and Maintenance much easier, again just as it does by using other types of Custom Properties.
For anyone interested in a workaround until such variables are available, see Using an Alert Custom Property in that Alert's Action with credit there going to fdamstra for asking the question and rob.hock for providing the answer.
If I missed that there is already variables available for this, please let me know.
THANKS
