Replacing a missing post while maintaining the same link?

Hello, I’m trying to re-post an interview that was accidentally deleted during a host migration a couple years ago. There are a few sites linking to the page, but the post is no longer there. I’d like to re-post that content and have it live at this address:

https://lasnark.com/2009/09/22/aimee-mann-interview/4115

I assume I can just date the post 9/22/2009, but is there an option to add the 4115 post number?

Thank you.
