How do I insert subtitles for a short movie with the Adobe CC?

I now know how to add the normal subtitles, but I need that one step more complex. For example, Netflix sees subtitles "stacking" as soon as two people say something in quick succession or talk at the same time (so the dialog texts overlap, for example, in a dispute). The option that two different subtitles are shown on top of each other at the same moment I have not found yet.

No idea, with VLC that goes by separate file

Google is extremely difficult to use, only good that there's good question…
