For enabling it for multiple instance, in the dialog screen, you need to tick the check box named Enable Multiple Instances
After doing this, when you display the settings screen, in the top-right corner, each source will display an info such as: Instance #1, Instance #2, … and the settings will be stored separately in the registry.
