Specifying database replica in blueprint

I wasn’t able to find out how to specify database replicas in the blueprint specification - is it not currently possible?

Hi David,
At the moment it’s not possible to create a read replica with blueprints.

Is this still not possible?

You can now add a replica from the Render dashboard:

Note that replicas are only available for standard plans and above.

Can we add them via blueprint now? Its been a year.
