Replicate sample data from prod database to dev database

I have two databases in Atlas; prod and dev. In order to keep the dev up-to-date with the latest data, I would like to copy approximately 20k documents from the prod database to the dev one.

The only requirement is that the articles are of the latest date. In addition, is it possible to automate this process. For example, every 3 months, refresh the dev database with the latest from prod.
