Can I use the DeployReport option when deploying a dacpac through Release Management

I'd like to be able to setup a WinRM dacpac deployment task in MS Release Management to create a report of the schema compare and not actually deploy the database. Then I could have an environment approval and abandon the deployment if unexpected changes are reported. If the changes are as expected, the next environment would actually deploy the database.

Is there a way to do that using the available WinRM DB deployment task? If so, how?

'Publish' is hardcoded in the task script, so we wound up creating a powershell script that does this. Mostly modified the relevant code from the task (https://github.com/Microsoft/vsts-tasks/tree/master/Tasks/SqlDacpacDeploymentOnMachineGroup) and imported the utility file used by the task (https://github.com/Microsoft/vsts-rm-extensions/blob/master/TaskModules/powershell/TaskModuleSqlUtility/SqlPackageOnTargetMachines.ps1). Then just changed the hardcoded value and added the output file parameter. Then we read in the report file and display it in the release log for the powershell task. abest's comment is a good idea, but it looks like we don't currently have that task available at our site.
