I merged 4 files (w/ "Open for translation"), but how can I tell which one I am currently working on?

Question

I can't see any indication of this anywhere. 
 
 Since they are Excel files (which Studio can't preview)), I need to open the relevant one in Excel for previewing, as they contain important contextual info regarding the amount of characters permitted in specific columns.
