How to hide open apps from other workspaces in the panel?

I asked Carmar and he suggested looking at this thread and jgordons response:

How to get a "new" workspace?

The only way I’ve found to do this is to use the Zorin Dash extension (I think it’s the Gnome 3 layout) and using Tweaks, switch on Isolate Workspaces. This allows me to have the activity bar only showing the applications for the current workspace. [workspace1] [workspace2]
