Automated Replication of RDS Cluster Snapshots

[ghost]

Dear AWS CDK community,

I'm trying to find a simple way to copy Automated RDS Snapshots of type “DB cluster” to another region in the same aws account.
Current setup is simple: AWS RDS Cluster with Backups activated to run daily on given time window.

The backups are created as Snapshots, and if I select a snapshot and click “Actions”, I can copy it to the target region. Why I need is an automated way to do that.

Currently, I'm considering a lambda function to do this task.
Is it possible to achieve these settings in AWS CDK without any additional lambda?

P.S. I have another setup where there's only one RDS Instance and the Automated backups show up in the “Automated Backups sections” and can be replicated to another region.

Thanks in advance for any help.

UPDATE
Seems AWS does not provide a simple way to do it. So, going with own implemented Lambda.
