/// Configures single source property's visibility, possible modification callback and callback payload data, as well as whether the property should be enabled
/// - Parameters:
///   - property: The source property to change
///   - enable: Whether the source property should be enabled (user-changeable)
///   - visible: Whether the source property should be visible
///   - callback: Pointer to a function that will be called if this property has been modified or the properties are reloaded
///   - capture: Optional reference to ``OBSAVCapture`` instance
