The section number of document contents can be exported to an Excel import template using the add-in. This feature was delivered in a previous version, but it seems it only happens on the first synchronize. If contents were rearranged, deleted, or created in the live document, then synchronizing should recognize that and update section numbers to match. It would be great if it would correspondingly rearrange the rows as well. Content which is created from the sheet should also show its new section number, each being one more than the last section by default.
