NSubstitute method called multiple times with specific sequence of args?

I want to check that a specific method is called N times, first with arg x1, then x2, then x3, etc. and finally with arg xN. I know it could be done like this:

Received.InOrder(() => {
    subst.MyMethod(x1);
    subst.MyMethod(x2);
    subst.MyMethod(x3);
    // ...
    subst.MyMethod(xN);
});

But can it be done in some way that simply lists the sequence of arguments?

Something like this (conceptual):

int[] args = {x1, x2, x3, /*...*/ xN};
subst.Received(N).MyMethod(Arg.Is(args));

Here's an implementation with InOrder but I consider it a workaround:

int[] args = {x1, x2, x3, /*...*/ xN};
Received.InOrder(() => {
    foreach (int i in args)
        subst.MyMethod(i);
});

From comment above:

The NSubstitute API does not have a method for doing this. To me the foreach method is clearest; it shows exactly what is expected for the test to succeed. You could write a method to package up this logic if you need it frequently, but while it may make it a bit more concise I don't think it will make it any clearer.
