Because sometimes i mux series of files with same prefix ; for example i mux with title : "Name of show - SXXEXX - title of episode", and after muxing, when i want to mux next episode, instead of typing again "Name of show - SXXEXX+1 - title of episode", i copy it before making new mux, then paste it into new mux, thus it's easyier to stay in Global Settings instead of getting back to Input, then Global Settings
I don't know if i'm clear
