Movies with multiple parts

Duly checked the thread but could not find an answer.
There are some movies that have separate parts (e.g. Fassbinder's Berlin Alexanderplatz, Visconti's Ludwig etc.).
Noted that scraper only finds the first part, if any.
In order to add the remaining parts, I have been doing so:
- In the movie's folder I create a subfolder for each part;
- Copy the existing nfo from Part 1, paste it in each other folder and rename them to match each part's names;
- Edit entries' titles to match the part (usually as {title} - {subtitle});
- Directly edit each nfo SORTTITLE as {name}.nn;
- In the context menu, Scan folder for new content... for each part's folder.

Some manual work, but it's OK - there are not many.
However, there are two items that are stubborn and resisted to all my tricks.
- Kenji Mizoguchi's The 47 Ronin (tt0033654; 45978) and
- Aleksandr Sokurov's Confession Episode 2 (tt6261034).

I have tried everything but Ember still refuses to add an entry for Part 2.
How to do it?
Or else, is there a more "scientific" way to deal with movies in multiple parts?

Manually edited nfo for it with all pertinent data, tried Scan for new content..., eliminated Part 1 from database etc. etc. but no way.
