Frankly, someone™ should put in the work to make

\version "2.25.13"

{
  \clef bass \omit Staff.Clef
  \omit Staff.TimeSignature
  \stemDown

  << d,4 d2 a >>
  << d4 a2 f' >>
  << e,4 c2 e \fermata >>
}
%%%%

just work.  There is an additional bit of ickiness for per-note
articulations as compared to per-chord articulations since per-note
articulations would require an extra < > bracketing around the note in

Also you need to take care when using that construct in \relative since

pitch to the next note while << ... >> conveys the _last_ pitch.  So
switching between the two does involve some editing.
