Skip ACL apply during multipart copy operation

[shivakumargowda12]

I am trying to make use of s3cmd to copy a large object using multi part copy operation.
Here the source and destination servers are from different S3 vendors.
Since Identity of a User/Group would different between different vendors, multipart copy would fail while trying to apply ACLs of source bucket onto destination bucket.
Is there a way, we could skip ACL apply during copy operation ? As there is option to make public by providing --acl-public parameter.
