I have a situation where in an s3 bucket I have prefixes of several accounts and within those prefixes, I have files that contain arns that I need to use in my serverless file.

However, I’m stumped when it comes to how to use the current account in the s3 variable.

For example, how would I do something like:  
Resource:  
- ${s3:/\<account\_id\>/\<filename}

Is there anyway I can do this?

Thanks!
