Visual Studio find un-overriden pure virtual functions

Question

I am designing a class which inherits from a few interfaces, each with many pure virtual functions. I want to be able to instantiate my class so I need to override all of the pure virtual functions it inherits. I would appreciate a way to highlight or display the functions I have not yet overridden in my derived class but I have not yet found one.

I've tried generating a class diagram to visually compare the functions in the derived class and the base classes. However, I'd prefer a more direct and elegant solution, especially as the project grows.

Here's a generalized example:

Foo.h

class Foo {
public:
  virtual int foo1() = 0;
  virtual int foo2() = 0;
  virtual int foo3() = 0;
  virtual int foo4() = 0;
  //...
  virtual int foo90() = 0;
};

Bar.h

class Bar : public Foo {
public:
  int foo1() override {
    return 4;
  }
  int foo2() override {
    //do stuff
  }
  //darn, I lost track of what I still need to implement!
};

Does Visual Studio have a way to automatically display which functions are still not overridden? Alternatively, if there's a compiler option to display an error/warning for each of the abstract functions that are preventing the instantiation of my class then that would be just as helpful.

Let's say you have:

class Foo {
public:
    virtual int foo1() = 0;
    virtual int foo2() = 0;
    virtual int foo3() = 0;
    virtual int foo4() = 0;
};

class Bar : public Foo {
public:
    int foo1() override {
        return 4;
    }
    int foo2() override {
        //do stuff
    }
};

And you instanciate Bar:

int main()
{
    Bar b;
}

Visual Studio produces a C2259 compilation error, tells that you cannot instantiate abstract class and highlights ("due to the following member") that foo3() and foo4() are abstract:
