Custom script for Pages footnotes

I have a genealogy program (Reunion) that outputs Pages documents, but they add the notes to the end as paragraph text unconnected to the superscript numbers in the text. As a result, I have to copy and paste each of these notes into a newly-created footnote to be able to get the flexibility of a true footnote in my documents so that I can use the standard genealogical format. I've tried other genealogy software but they deliver worse reports (RTF)! Therefore, I am looking for a script that will: 1. Find superscript notes in text, find the associated text blob at the end, and make it into a footnote. 2. Ignore where a superscript number in the text is the same as another, change it to be incremental with the same note text included (e.g., text may have notes in the text numbered 1, 2, 1 because #1 is the same note text. But I need them to be numbered 1, 2, 3 and just use same text in note #3 from #1. See the attached sample. 3. Nice to have: Within a family generation list (number i, ii, iii etc.) the children are supposed to be numbered sequentially according to birth date, but this program just lists them according to the order you input them (!). If this issue could be fixed as well with the script that would be amazing.
