I'm using Azure DevOps Server 2019 update 1.1 on premises. I'd like to customize Steps of Test Case work item described here: https://learn.microsoft.com/en-us/azure/devops/test/create-test-cases?view=azure-devops-2019#create-test-cases
For instance, is it possible to add a new custom column in addition to default columns Action, Expected result and Attachments? If yes, how is it possibile? I'm using xml process model, is it possibile to customize columns of Steps by xml (or for instance do I have to use SDK)?
