Fairly new to cloudformation templating but all I am looking to create a template where I create a S3 bucket and import contents into that bucket from another S3 bucket from a different account (that is also mine). I realize CloudFormation does not natively supports importing contents into S3 bucket, and I have to utilize custom resource. I could not find any reference/resources that does such tasks. Hoping someone could point out some examples or maybe even some guidance as to how to tackle this.
Thank you very much!
