Batch copy-pasting track names.

Hello, new member here who's been fondly using Mp3tag for several years (thank you guys for making my life a whole lot easier where music files are concerned!).

Need assistance on the following matter:

Say, I have this soundtrack (FFXIV A Realm Reborn http://vgmdb.net/album/44019) with all the tags/filenames in English; and wish to add / insert the Japanese song titles alongside their English counterparts; is there any way I can copy-paste all the Japanese titles using one action, instead of
slogging through the hundred-or-so tracks, one at a time?

Help is very much appreciated, thanks in advance!

How do you align the translation pairs?
Or how should MP3tag know which translation belongs to which file?
If you have the filename, you can use the function
Convert>Text file - Tag
