Is there a way to indicate if an app is open in the current or another workspace?

Question

Is there a way to have the little orange dots at the side of the dock indicate whether the app is in the current workspace or another? If for example two instances of Firefox were open in different workspaces at the same time, one dot should be orange and the other one gray.

Currently, I use a compromise by completely isolating the workspaces according to this description: Separate workspaces in Ubuntu 18.04 Desktop ; however, it isn't ideal either as it is the other extreme.

Any simple solutions?

The behavior I am looking for was actually the default mode in Ubuntu 16.04 (Unity). Instead of dots subtle triangles were used: example-image-of-old-dock-behavior

Unfortunately, no. There is currently no option to allow having the marker for running windows have a different color if the window is not on the current workspace. The Ubuntu Dock is based on the Gnome Shell extension "Dash to Dock". Filing a feature request with the developers could cause them to consider adding this feature.
