Multiple Notifications

Hi. With the ui.display-notification command, is there a way to have multiple notifications displayed together? I'm using the command in a workflow that runs when the app launches. So far I'm only able to display a single notification, but I think there are scenarios where it would be useful to have two displayed. Maybe an info notice and a warning notice, say.

The documentation mentions this arg, but seems it's only applicable for mobile, not web…

Thanks
