How to run filters on dotnet tests

I have a build in VSTS, as follows:

You can see from the screen shot there's a test step to "Test and generate code coverage". It uses this command:

/p:CollectCoverage=true /p:CoverletOutputFormat=cobertura /p:CoverletOutput=$(Build.SourcesDirectory)\TestResults\Coverage\coverage

Which allows the code coverage report to be generated. I have added "Categories" to my xUnit tests with my defined Trait (such as integration or unit), to allow me to filter tests during build/release. Example would be:

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using Xunit.Abstractions;
    using Xunit.Sdk;

    /// <summary>
    /// Decorates a test as a Unit Test, so that it runs in Continuous Integration builds.
    /// </summary>
    [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method)]
    public sealed class IsUnitAttribute : AICategoryAttribute
    {
        /// <summary>
        /// Initializes a new instance of <see cref="IsUnitAttribute"/>
        /// </summary>
        public IsUnitAttribute() : base("Unit") { }
    }

    /// <summary>
    /// Decorates a test as an Integration Test, so that it runs in Continuous Integration builds.
    /// </summary>
    [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method)]
    public sealed class IsIntegrationAttribute : AICategoryAttribute
    {
        /// <summary>
        /// Initializes a new instance of <see cref="IsIntegrationAttribute"/>
        /// </summary>
        public IsIntegrationAttribute() : base("Integration") { }
    }

I only know how to apply a filter in VS-Test step, as follows:

But not when I'm testing using dotnet:

I only know how to build code coverage using dotnet (and not VS-Test)… I want to do both! How do I:

a) Add the commands to the VS-Test to generate the code coverage, the same as I do for dotnet using the command above.

OR

b) Apply the filter to the dotnet Test step?

Any pointers much appreciated!
