How to export audio stems, one wav file per each track?

I have a project with one stereo track and one mono track.
I want to export each of those 2 tracks as one wav file. So that I get one stereo track and one mono track separately.
This does not seem to be possible which I can't believe. I must be missing something.
I tried all combinations on the audio page. I tried rendering with and without the "render one track per channel" option.
I tried "Ouput track" set to Main stereo, Timeline Track, All Timeline tracks.
"All timeline tracks" comes close but what it does is creating one single file. When I import that back into Davinci, it has each channel as one mono track. So I'm geting 3 tracks, 2 mono channels for L/R of the stereo track + the additional mono channel.
Is there no way to simply export all audio tracks in a timeline as separate stems?
