hi @Andre_Malotaux ,
It is a well known issue and I do not consider it as a bug, but as a temp hick up. Temp because the day we have real 2WS (stage 4) we will distribute data easily over documents, that is not for anytime soon, but in the works.
You can use cross docs and share filtered views or use a webhook based logic (there are packs) to push data to other docs. I do understand you would liked to have read something different, but this it is for now.
Sorry for bringing you the bad news, cheers, Christiaan
