Ending slur on a different voice

[Cameron Hall]

Here is a short simplified excerpt of a piece I'm trying to notate. I
need a slur to start on the quarter note C and end on the D in measure
3. However, it doesn't seem possible to start the same a slur in a
single voice and end it in a split voice. Is there an easy workaround
for this?

%%%
\version "2.24.4"

\fixed c'' {
  \time 3/4
  r2 c4~( |
  c8 d e f g a |
  << { b a g f e d) } \\ { r4 <e, g,> q } >> |
  c2. |
}
%%%

Thanks,
Cameron
