Single Article Recipe

Hello all,

I'm trying to find a solution for this use-case:
I want to read one particular article later -> Save it to Pocket/Instapaper -> Read in on my Pocketbook.

I tried with Calibre "Fetch News" feature. However, this creates collection of articles.

Since Pocket recipe is not working at all, I tried configuring Instapaper.
Changed max_articles_per_feed = 1. So far so good.

Now I'd like to each epub created to have title of the article as title, and Instapaper as the Author.

Is it possible? (Without the need to do it manually after creation)

Thank you!
