Multiple instances of same articulation/bowing on one note

[Ahanu Banerjee]

I'm trying to put the same articulation both above and below one note. (My document has one set of bowings above the staff and an alternate set below the staff, and occasionally they both need the same marking.) 

The workaround I currently have is creating a second voice, which is a bit of a pain. Are there better solutions? Code below.

\version "2.24.0"

\language "english"

{ g8 g_\upbow ^\upbow g g % fails

  g8 g_\upbow ^\downbow g g % works

  % desired output:

  << { g8 g_\upbow g g } \\ { s s ^\upbow } >> }

Thanks,
