Yes, it is possible to connect a metric to a floating object, such as a text box, in the context of Sustainability Management within Workiva. You can connect content to an Sustainability Program metric from documents, which would automatically update the metric's value with the latest draft of qualitative source data. Notably, you can connect only body text and not embedded tables, charts, images, hyperlink URLs, or page or footnote numbers.
