You could use multiple \books along with \bookOutputSuffix:

%%%%
\version "2.22.0"

asdf = \relative f' {
 \time 3/4 \key f \major
 f4. c'8 g4 | a2. \bar "|."
}

\book { \bookOutputSuffix "C" \transpose c c \asdf }
\book { \bookOutputSuffix "Bb" \transpose bes, c \asdf }
\book { \bookOutputSuffix "Eb" \transpose ees c \asdf }
%%%%

(I might have messed up the actual transpositions, but you should get 
the idea.)
