Cloudformation package support --acl

Hi

I have a use case where I am using cloudformation package to upload source code to an S3 bucket. However this bucket is set up for cross account access. This seems to cause an issue when the account the bucket is in tries to access the source code as the bucket owner does have full control of the object. Would it be possible to add the --acl flag which is available for the S3 command and all the options that are allowed with that flag. My specific scenario is that account A is used to build and test the code however it uploads the source to Account B. Account B then deploys the code via codepipeline.

Thanks
