Automatically find first sentence each paragraph and add to collection

I’m using Scrivener for academic writing and I want to check my topic sentences across the document. Is there any way to run an “automatic” search or collection or compile that will find the first sentence of every paragraph and then add it to its own collection/document/file?

I could do a work around (each highlight manually each topic sentence) but I need to do this multiple times across long documents (6000-10000 words), so I’m looking for an auto solution.
TIA :slight_smile:

If you don’t use synopsis, you could have automatic synopsis, which will show the beginning of each document. Split the document so that each paragraph is its own document. If you then use Outline view and show synopsis, you would get roughly what you want, I think.
