Creating an Alias Desktop

Is it possible to associate an Alias with a Desktop? I’d like to open an Excel database into its own Desktop but cannot figure how to do it. I obviously can Open an empty Excel workbook. Any suggestions please.

I’m not sure exactly what you mean - do you want to open an excel file, and have it appear on a pre-assigned desktop? You can do that by assigning excel to a particular desktop in Apps prefs. But note that all Excel documents would appear on that desktop.
