[Plugin: Amazon S3 for WordPress with CloudFront] delay Mirroring by a few seconds?

hello, is there a way to delay the mirroring to s3? I use automatic cropping and watermark for my pictures but they get mirrored to s3 before the watermark gets printed on them, thus i find the pic on my server watermarked but the one on s3 isn’t. need to delay mirroring by a few seconds, how to do that?
