On R2022x, if I use shared/reusable representations in native Client they are displayed with an arrow on the icon. So you can identify it as a reusable one at first sight.
 

The small arrow on the icon indicates that the drawing is a shared one and could be used under another physical product.

In the Dashboard, e.g. in the product structure explorer, there is no arrow nor any other indicator for a shared representation.
 

In the picture you can see the same drawing under two different physical products but you cannot identify the drawing as a shared one.

Is there any possibility to identify a shared representation in dashboard apps?
