"Play sound" only offers system sounds

When I choose the “Play sound” action in a smart rule, it only offers sounds that are in /System/Library/Sounds — it does not allow me to choose the sounds that are in $HOME/Library/Sounds.

As macOS does not allow me to add sounds to the system sounds folder, this means I am unable to have a smart rule play the sound I actually want.

Would it be possible to also support sounds in the user’s own Sounds folder? I’m guessing there are potential issues where multiple users have access to the same database and they don’t all have the same sounds installed, but DT3 could fall back to the default system sound in that case.

The request is noted, with no promises.
