Usage with existing tables

Hello, I find the need to set my provider.iamRoleStatements.Resource to a pre-existing arn.
However, I would still like to define the resource within my serverless.yml in order to facilitate local development with serverless-offline.

When I have these defined I can no longer deploy via sls deploy:

> An error occurred: UsersDynamoDBTable - users-table-dev already exists in stack [...]

Is there a way to define my dynamodb resources so only serverless-dynamodb-local will use them, and not `sls deploy`?

Start with the serverless.yml resource definitions and the serverless-dynamodb-local integration, then compare how serverless-offline and sls deploy process them. Determine whether local development can use the existing DynamoDB definitions without attempting to create them during deployment, and verify both workflows against the reported existing-table error.
