I have a number of

arrangements  with vertices v, edges e and faces f. I tag each face in each
of the arrangement properly (e,g, {A} face means that the face is inside the
arrangement A)

Now, I want to overlay all these arrangements together, and for the
resulting arrangement, I want each face will have a tag of the original
arrangements. How to do this? My idea is that I want to use
http://www.cgal.org/Manual/3.3/doc_html/cgal_manual/Arrangement_2_ref/Function_overlay.html#Cross_link_anchor_811
overlay  function for the first two arrangements to find a resulting
arrangement, and use the overlay on the resulting arrangement and third
arrangements, and so on.

But do we have a more efficient way of working?

No.
