How to reuse an origin in multiple CloudFront behaviors?

[ameotoko]

CloudFrontToS3 construct internally creates a new S3Origin for the default behavior from a bucket provided in the props. I am trying to add an additional behavior, but can't find a way to assign it the same origin. Is it even possible with CDK?

This is the code in question (it's from the https://github.com/aws-solutions/video-on-demand-on-aws-foundation):

const cloudFront = new CloudFrontToS3(this, 'CloudFront', {
    existingBucketObj: destination,
    insertHttpSecurityHeaders: false,
    cloudFrontDistributionProps: {
        comment:`${cdk.Aws.STACK_NAME} Video on Demand Foundation`,
        defaultBehavior: {
            allowedMethods: AllowedMethods.ALLOW_GET_HEAD_OPTIONS,
            compress: false,
            viewerProtocolPolicy: ViewerProtocolPolicy.REDIRECT_TO_HTTPS,
            responseHeadersPolicy: ResponseHeadersPolicy.CORS_ALLOW_ALL_ORIGINS_WITH_PREFLIGHT
        }
    }
});

I was able to get the targetOriginId from the created distribution, but cloudFront.cloudFrontWebDistribution.addBehavior() only accepts IOrigin and not strings. I wasn't able to find a way to create reference from id either.
