Buttler would win his 50th one-day international cap in England's World Cup opener against Australia on Saturday.
Buttler said that he was ambitious to score bigger scores and didn't want to be pigeon-holed as someone who could only finish an innings, the BBC reported.
Admitting that though he is content in his role as finisher, the wicket-keeper batsman further said that he would want to be someone who could bat for 35 to 40 overs and get big hundreds, the report added.
