With the latest release, you can no longer highlight just items in the dimension column of a freeform table. It will always highlight the entire row (you can, however, highlight just the metric columns). This is really problematic when trying to copy things like page names or URLs.
You can always select individual page names or URLs from left panel in Workspace. You will just search for that dimension and click on '>'. With that, all the values for that dimension would appear. You can then drag and drop or copy those line items and use it anywhere. Please see below screenshot.
