Toolbar tab desc. too lengthy

I often times have multiple spreadsheets open at the same time and navigating can get a little tedious. When i open a spreadsheet, the excel tab within the toolbar at the bottom of the screen will be listed as "Microsft Excel - Book1" for example. I already know that it is a Microsoft Excel spreadsheet by the small little green icon within the tab.

Is there a way to shorten the name of the toolbar tab so it will just display "Book1"? I attached a picture detailing the issue in case if i wasn't clear.
