At present although an encryption type of aws:kms can be specified for the type of server-side encryption a key id cannot be specified. If an organisation has multiple Amazon KMS keys, there is no ability to specify which one should be used to encrypt the files.
As per the AWS documentation a SSEKMSKeyId property can be assigned that specifies which key should be used.
This functionality greatly opens up the plugin to organisations that have multiple KMS keys.
