To combine labels with multiple UNC paths, configure the additional paths by using the same label.

An example configuration with multiple labels combined with multiple UNC paths:
<config>
  <profileArchivePath label="APAC">
    \\fs-21\DemUsers$\[UserFolder]\Archives
  </profileArchivePath>
  <profileArchivePath label="APAC">
    \\fs-22\DemUsers$\[UserFolder]\Archives
  </profileArchivePath>
  ...
</config>
