avoid member move boilerplate in move constructor?

Sometimes you still want the default move-constructor behavior (member-wise move), but also want to modify the moved-from object. Take the following scenario, for example

class Base{...}; // some move-constructible class
class Member{...}; // also move constructible

class Derived : public Base
{
public:
    // does member-wise move, but nothing more
    // Derived(Derived &&) = default;

    // does member-wise move, same as default
    // and also modifies `other`
    Derived(Derived && other)
        : a(std::move(other.a))
        , b(std::move(other.b))
        , ... // the rest of members
    {
        other.put_into_invalid_state_or_something();
    }

    //...............................................
    //      More functions
    //...............................................

private:
    // a lot of members...
    Member a,b,c,d,e,f,g,h,i;
};

This may be a silly question, but is there any way to avoid writing the move for each member?
