Amazon S3 Requester Pays Header Checkbox

I would like to access an Amazon S3 bucket which is not in my own AWS account, and has "Requester Pays" enabled. https://docs.aws.amazon.com/AmazonS3/latest/userguide/RequesterPaysBuckets.html

I would like to configure WinSCP to send the x-amz-request-payer request header with a checkbox labelled "Request Payer: Requester" to match the label used in awscli.

I can provide IAM access key and configured buckets for testing by DM.

Thanks for your post.

I have added this request to the tracker:
