You can write a music function that takes a note as an argument, and
returns the override, the note and its markup.

%[not tested]
\version "2.7.1"
tcdown = #(def-music-function (parser location note) (ly:music)
           #{
              \once \override TextScript #'staff-padding = #2
              $note _\markup \column { T C }
           #})

{ \tcdown a }
