smart division of tablenotes at long table between pages

Question

as background see my answer on this question.

i wonder, if it is possible that tablenotes be (automatically) split between pages on the way, that on each pages are present only items which are used on this pages. for given example example that on the first page tablenotes contain only items from 1 to 7 and on second package only items 1, 8 and 12.

for start i would be happy if it is possible to define two tablenotes and use the first one on the first table page and the second on the second page containing longtable.

This is the easy solution with many TableNotes.

Here I rewrote the TableNotes environment and \insertTableNotes to take an additional mandatory argument to name the table notes. Caution, there is no check, if a table note with a specific name (already) exists.

You can have as many table notes as you want (see second page of example). But of course there are only two feet for a longtable, so you can only have two differnt sets of notes. (If I could figure out, how to change a foot mid table, then there may be a chance to automate the notes. But so far, no luck.)

The result:

The code:

\documentclass[11pt, oneside]{book}
\usepackage[a4paper,
            hmargin={2.5cm},
            top=2.5cm,
            bottom=3.5cm]{geometry}
\usepackage{caption}
\usepackage[table]{xcolor}
\usepackage{array, ltablex, threeparttablex}
    \newcolumntype{C}{>{\centering\arraybackslash}X}
    \setlength\extrarowheight{3pt}

%-------------------------------- show page layout, only for test
\usepackage{showframe}
\renewcommand\ShowFrameLinethickness{0.15pt}
\renewcommand*\ShowFrameColor{\color{red}}

thank you very much for your answer. it fulfill my minimalistic expectation. however, testing it, i notice table behavior for which i didn't aware so far and for which i don't know a cause yet. to be more specific, i need to investigate more scenarios of table use. i will inform you about my findings. — Zarko, Nov 09 '17 at 03:12
problems in testing of your solution has source in my misunderstanding how works longtable and have not any connection with your solution. — Zarko, Nov 09 '17 at 06:42
