If the items are manually ordered (not sorted), you could use a Title Expression like
[Tree Order] || ' - ' || [Item Title]
But the displayed title value is not dynamic -- you would need to rename existing items for the displayed title to show the order + title (and you would need to rename again after reordering items).

Another option would be to export to XML -> numbered HTML outline:
