How to change the order of files that appear in ExportToWord.docx

I want to control which files the repetitions are removed from the ExportToWord.docx file. It seems that they are deleted from the files that appear later, so I would like to control the order in which the files appear, but I do not know how to do this. The order in the [Project Properties] dialog seems to be different.

Is there any way to do this?
