Filter JSON as part of Notification

[tanebufton]

Currently I am monitoring a JSON API in order to identify when a product is in stock.
As part of the monitor, I am looking at the entire JSON response for certain fields to see if they change, however as part of the response there is also a quantity field which provides the stock levels.

It would be nice if possible to be able to filter on a Whole JSON path (e.g. json:PageData) - However be able to parse part of the response that is extracted within the notification that is sent (e.g. a notification of "Item is in stock - {PageData.Quantity] remaining")
