AWS Serverless Application IAM Role

When creating an AWS Serverless Application (Template ASP.NET Core Web App) in Visual Studio 2019, the "Publish to AWS Lambda" dialog does not allow us to specify an IAM Role.

In order to set the IAM Role we have to manually modify the aws-lambda-tools-defaults.json file and set the "function-role" : "arn:aws:iam::xxxxxxxxxxxx:role/my-role"

Is it possible to include the Lambda Role in the "Publish to AWS Lambda" dialog box?

Start with the Visual Studio 2019 "Publish to AWS Lambda" dialog for the ASP.NET Core Web App template and compare its options with aws-lambda-tools-defaults.json, especially the existing "function-role" setting. Trace how publish settings are read and applied; done means the dialog accepts an IAM Role and uses it during publishing without requiring manual JSON edits.
