Modifying project properties of custom project system

I have tried to create a custom project system by walk through https://msdn.microsoft.com/en-us/library/vstudio/cc512961.aspx and succeeded. And now I want to modify the project properties of this created project system. The second part of this walk through is guiding to create property pages for solution properties. (Solution Explorer-> Right Click on Solution and select Properties) I don't want to modify solution properties, I need to customize project properties (Solution Explorer-> Right Click on Project and select Properties) by adding new tabs and other items for my custom project system. Please help me as soon as possible.
