Please add the ability to outline or add a dividing line between each element of grouped elements within ArcGIS Dashboards.
Grouping elements improved the functionality of my Dashboard because I have multiple pages of serial charts and pie charts. Before grouping the elements together, I embedded multiple dashboards into one dashboard. By using that method, the user had to choose a category selector each time they moved to the next embedded dashboard to continue filtering the data. Now, by utilizing the grouped elements method, I was able to group a page of elements and then stack each grouping on top of each other. The user now only has to choose their category selector one time to filter the data.
However, the problem now is that the grouped elements have no barrier between them which makes each element confusing.

Dashboards with grouped elements would be easier for the user to interpret if we are able to add an outline around each element, similar to how it looks when editing:

Here's an example of how my dashboard looked before I grouped the elements:

Adding a dividing line between each element and editing the color and line weight would greatly improve Dashboard capabilities.
