Feature request: Option to limit pinned applications to the workspace

[insolite]

A checkbox + dropdown option for the pinned item to make it visible only on the specific workspace. The app will still be visible if launched but not visible as a pinned item.

Use case:
I have 2 separate workspaces for work and personal stuff. So I pin and use different apps for them (or the same apps with different CL parameters). It would be extremely convenient to clean up each workspace from the launchers that are not in the context of the workspace.

Example implementation:
A form that opens in dialog from the context menu of the pinned item at "Properties -> Edit Workspace". The form would contain:

• A checkbox like "Single workspace"
• A Dropdown/Select component with workspaces. Activates when the checkbox is checked.
