I would love to use s3deploy instead of aws s3 cp, but I have to specify aws s3 cp --sse aws:kms --sse-kms-key-id arn:aws:kms:my-key in order to transfer files into my bucket. I do not see any options for using a customer-managed KMS key with s3deploy. If you could please add this feature, I would be able to take advantage of your tool. Thank you!
