On the collision report for each experience it currently listed ALL activities that clash with the experience from all workspaces you are wanting to publish based on the mbox and page URL. But there are no filters so its a pain to check if there are any live experiences that are clashing. It would be great if on the collision report you could filter based on the target status (ie. live, inactive etc) as well as being able to filter by workspace (ie. default vs training etc)
