This can be done, depending on the window manager.
In my awesome window manager setup, super+tab always toggle the last 2 windows on the current tag (workspace). It's also possible to map super+1 to make an application be part of the current workspace (or open a new instance there). In this model, a window can be part of more than 1 workspace at the same time.
