This is a custom extension that I can sell at a reasonable rate which would include installation and configuration. The category selections are configurable and can be turned off. This is not sold as a “standard” extension in the store because it is a little bit complex to setup. Other than that it does work well and others who have purchased it are quite happy with it.
