Advanced Doc Import confused pagetree page hierarchy

Advanced doc import breaks headers in a word document into multiple Confluence pages where each header is used as the page titles.

For example, before importing into Confluence the hierarchical structure of a document looks like this:

The result would look ugly in pagetree macro because the sort mechanism in pagetree macro does not know anything about the original document hierarchy:

We need a way to make the resulting pages come out sorted nicely as to make the best use out of the import.

Perhaps a work around for this is to give each title a unique header and assign a number as to enumerate them and sort them automatically in the pagetree macro.

For example DocumentName-1, DocumentName-2 for each header and so on.
