With Angular Material Dialog, how to add multiple classes to the dialog?

Question

I can add a custom class to a MatDialog this way:

    this.dialog.open(MyGreatDialogComponent, {
      data: myGreatData,
      panelClass: 'my-great-class',
    });

Is it possible to add an additional class(es) to a Material dialog?

Quite simple to use an array of classes:

    this.dialog.open(MyGreatDialogComponent, {
      data: myGreatData,
      panelClass: ['my-great-class', 'my-other-great-class'],
    });
