Bases: Treat the active Workspace name as a variable

Use case or problem

If the name of the active workspace (in practice, the workspace most recently opened) could be used as a variable in Bases, I think it would make Workspaces more convenient — for example, by making it easier to list related files for each workspace.

Example

filter: file.tags.contains(workspaces.active)

Current workaround (optional)

Create separate Base files or MOC files for each workspace and save them as part of the workspace.
