Steemit: How to upload multiple blog posts to the platform?

We have an extensive archive with interesting blog articles (text and pictures). The posts get lots of Likes and Views at Google, Facebook, YouTube etc. We would like to publish a selected part of it on Steemit (> 2.000 posts). Is there a technical way to automatically upload multiple posts to Steemit? Maybe an API? Are there technical limitations or platform rules at Steem that do not allow this?

I'm looking forward to any helpful answer (will upvote).
