How to insert a field in a mail merge that returns multiple rows of a same "person" in a worksheet?

Example source worksheet:

Name: City:
A New York
A Miami
B New Orleans
C London
C Paris

In this example the mail merge will result in 3 pages (A, B, C), the merge field "Cities" should return 2 lines (New York and Miami) for A page, 1 line for B (New) Orleans, 2 lines for C (London, Paris), and so on.

This tutorial will work in this case?

I was using this concatenate sub:

But I want to know if there's a way to do that within word mail merge.


Thanks.
