Can we use Amazon S3 URL of Parent template in TemplateURL to call Child template

Question

I have a Parent template and it is calling the child template.Both the templates are in a same S3 Bucket.Now,my requirement is to call the child template whenever a stack is created from the Parent template.Currently,I am using the TemplateUrl and giving the path as https://${QSS3BucketName}.s3.amazonaws.com/ and accessing the child template.

Requirement: While creating the stack,I am giving the Amazon S3 URL of the Parent template.Is it possible that I can use the Amazon S3 URL path and give reference in Templateurl to call the child template.
