Execute functions with roles specified in template

I have a function that sends an email with ses, and I specified in the template, among others:
```
Resources:
EmailFunction:
Type: AWS::Serverless::Function
Properties:
Policies:
- CloudWatchFullAccess
- AmazonSESFullAccess
```
Remotely, this works, as an implicit role is created with the specified policies attached. But locally, it tries to execute as the user specified in ~/.aws/config, and fails, as I haven't attached SES policies to this user. It would feel more consistent to me if it used the same role locally and remotely, is this possible?
