Epiphany WorkFlow isn't quite what you asked for, but I do believe you would find it a reasonable fit for your needs. Its output can go into Apple's Pages for final formatting, and it's free until Jan. 1, 2021. There after just $20 for a permanent copy. Disclosure: I wrote it. https://apps.apple.com/us/app/epiphany-workflow/id1490449900...

I admit that this looks like a bit of an ad, but I think it's fair use. If I offend anyone, I apologize.
