Hi @Miller, Amber,
I read your description, and I searched for relevant documents or resources and JavaScript API, but since the Edge workspace function has just been launched, there is no relevant function that can filter some links so far. As you know, now the 'Default workspace for external links' settings can only open all external links into the workgroup. So, my only suggestion is that you can click "dislike" in the workspace to submit feedback. You can also refer to this official document.
