Using dynamic tags within text

So I created some dynamic tags. After my Gravity Form is submitted it creates a post. The post has the contents of the dynamic tags listed under the body so this is all working fine. The question is, can I insert a dynamic tag within other text? For example, I have a dynamic tag called "author" and "publishing_date". In my body of text, I want to use the sentence "The book was written by {dynamic tag author} in {dynamic tag publishing_date}.
