How to I bring an bulleted list (or any type of list) into the Outliner and have it break it up into outline items?

If I paste the entire list (brought over from OneNote) into Outliner, it appears as one “block.”
I’d like it to separate the list into individual outline items. Is there a way to do this without individually cutting and pasting?

Edit: ok, it seems like I just need to copy it to a .txt file and import/split it.

Now the issue seems to be, how do I divide the list so they’re imported as synopses or content? I don’t want the list simply to be imported as titles with blank content.

Can OneNote export as OPML? That’s the standard format for sharing outlines.
