Keep the structure of the text when publishing to Insagram

When posting to Instagram, it would be great if we could create a post with paragraphs, spaces, hashtags, e.t.c, and when we post it to Instagram, know that the structure of the post has not been changed.

At the moment If I create a post with two paragraphs, bullet points separating each paragraph, and then a segment of hashtags at the bottom, it usually posts to Instagram as one big paragraph of text and hashtags.
