Add track disambiguator to title?

[Gwouigwoui]

The question is in the title: is there a way to add track disambiguators, if present, to the title of tracks (for albums like this one: https://musicbrainz.org/release/5f20273d-a1c9-4c7f-a9fd-8fcd2f58a4eb)?
Thanks!

Do you mean ex. "(mono single)" here? https://musicbrainz.org/recording/ca25a870-6b8d-4c44-b684-a40644c26079

And you want them in the metadata tag for title?

Exactly!

I've taken the rewrite plugin as a base, as I also needed the extra information. Please see my code below, currently only the title is working.
I got the album disambiguation also working once, but undid my changes by accident.

"""Appends disambiguation information to track and album titles for path
formats.
"""

from beets import library, ui
from beets.plugins import BeetsPlugin

class MyRewritePlugin(BeetsPlugin):
    def __init__(self):
        super().__init__()

        # Add new template fields for track title and album title with disambiguation.
        # this one works
        self.template_fields["title"] = lambda item: self.append_disambig(item, "title", "trackdisambig")
        # this one too, but has no effect on the actual tag
        self.template_fields["album"] = lambda item: self.append_disambig(item, "album", "albumdisambig")

        # not working at all, got it working once :-(
        # self.album_template_fields["album"] = lambda album: self.append_disambig(album, "album", "albumdisambig")
        
        # print(self.album_template_fields["album"] )
        # print("RewritePlugin initialized with template fields for title and album.")
    @staticmethod
    def append_disambig(item, field, disambig_field):
        """Append the disambiguation field value to the original field value.
        """
        print(item._values_fixed.keys())
        original_value = item._values_fixed.get(field, "")
        disambig_value = item._values_fixed.get(disambig_field, "")

        title_blacklist = ["live", "acoustic", "mix", "album version"] #

        if field == "title":
            for filter in title_blacklist:
                if disambig_value in original_value or (filter in original_value and filter in disambig_value):
                    return original_value
        # else:
        #     if disambig_value:
        #         print(disambig_value)

        if disambig_value:
            new_value = f"{original_value} ({disambig_value})"
            # print(f"Disambiguation applied: {original_value} -> {new_value}")
            return new_value
        else:
            # print(f"No disambiguation needed for: {original_value}")
            return original_value

Progress! So I could use your code to create a new plugin? Sorry for the dumb question...

Well, yes of course. The trackdisambig is working fine.
The albumdisambig on the other hand is kind of selective. Wasn't working on my Rammstein albums, but worked on the 2022 remix release of "Revolver".
