I was wondering if sth like this is possible in Dorico:
I created it in another program and tried to copy-paste it into a text-frame without success.
Dorico doesn’t support formatted lists, but you can easily add bullet points by typing Alt+8, and you can arrange your paragraph style such that you have a suitable indent on the second line to align with a tab stop on the first line.
yes ! That works…thanx Daniel 
…Alt+8 would have never found this…
