Search for files across printers

Right now the only way we have to search for files is when connected to a specific printer. Make it possible to search across all printers, and optionally filter based on printer type. For instance, I know I've printed this job before but I'm not sure which one of my MK4S printers I've sent it to. Right now I have to connect to each in turn and switch to the files tab and type the filename, then remember to clear the search afterwards. It would be great if there was one search on the main screen that would allow me to search for a filename on just the MK4S printers.
