I have a question about suppressing warnings added via Annotations

[gossandr]

Here is the scenario:

I have a stack doesn't always create any real resources (other than metadata) and is used to support flexible deployment configurations. In one configuration, the stack deploys a VPC. In another, it loads the VPC using the .fromLookup() method.

There is a warning added to display a message to a user if they are using a non-recommended configuration. This is done with Annotations:

let warnMessage = 'don't do this'
cdk.Annotations.of(this).addWarningV2('pipelineproject:VPCStack', warnMessage);

I know i can suppress warnings in code, but what I am looking to do here is put the suppression in the cdk.json or the ~/.cdk.json

Is this possible? From looking at this PR it seems like it was discussed, but unclear if this is possible.
