Is there any version of `INotifyPropertyChanged` for several changes?

Question

I read about the Observer pattern in the GoF book .

.Net Framework contains an interface INotifyPropertyChanged. Does the .Net Framework have a similar interface, but to notify of a change in a set of properties instead of notifying of a change in each property (to improve performance)?

I created such an interface INotifySubjectChangedfor my application (its event argument contains a set of changed properties), but maybe the .NET Framework already has it, and I invented a bicycle.

I published my simple source code on Bitbucket.org here . Perhaps a clearer what I want to do.
