I don't know what support MusicBee has for editing CUE sheets because I don't use them.
However, a CUE file is just plain text so I don't see any reason you couldn't just use Notepad or another text editor to change the track titles.
After checking what you're actually trying to achieve...
how would one edit the album title in the cue sheet, but only for selected tracks?
...a brief google tells me this isn't possible.
CUE sheet syntax includes a TITLE value that serves as both album title (if it's at the start of the file) and track title (if it's in a track entry).
It's not possible to assign an album title to a track.
Bee excellent to each other...
