Notification body data

[Pasa]

I would like to save notification body data to a column in a table using action behaviour? Is it possible? 
or expression to retrieve data from notification body to a column.

There's nothing comprehensively documented, but it's perhaps possible. See Use values from a previous step in a non-reusable action or task.
