Amazon CloudFront origin pull working with WordPress multi-site

Hi,

I’m setting up Amazon Cloudfront as my CDN. A problem I’m hitting is how to specify my Custom Origin Server when running WordPress multi-site.

For example, I have https://www.wp-site1.com, https://www.wp-site2.com and https://www.wp-site3.com

Do I need to setup an Amazon Cloudfront Distribution for each site? That will be a pain with many sites.

Is there a simple way to setup Cloudfront with a WordPress multi-site?

Thanks!
