In new projects on .net 9 I use Minimal API endpoints. Previously controllers had special Layout Renders ${aspnet-mvc-action} and ${aspnet-mvc-controller}, but endpoints do not have such a concept as action name and controller name. Endpoints mainly use metadata. For example, endpoint has methods WithDisplayName and WithGroupName, which I want to try to use similarly to display the action name and the controller name, but NLog does not have properties to render this metadata, only ${aspnet-request-endpoint} for render DisplayName.

orderTemplateGroup
    .MapGet("/{id:int}", GetTemplateHandler.GetOrderTemplate)
    .WithName("GetOrderTemplateName")
    .WithDisplayName("GetOrderTemplateDisplayName")
    .WithGroupName("OrderTemplateGroupName"));

My NLog.config for experiments

<target name="mainTarget" xsi:type="AsyncWrapper">
    <target xsi:type="Console" stderr="false">
        <layout xsi:type="JsonLayout" maxRecursionLimit="2" includeEventProperties="false">
            <attribute name="ControllerName"   layout="${aspnet-mvc-controller}" />
            <attribute name="ControllerName2"   layout="${aspnet-request-endpoint}" />
        </layout>
    </target>
</target>

How can I add additional metadata to a render? For instance, how can I add group name metadata to render?
Will new Layout Renderers be added to support displaying endpoint metadata?
