Automatically sell resources every turn

It could be nice to be able to sell resources every turn. I mean for exemple, I produce 100 titanium a turn and I want to sell 80 of it every turn so that I produce 20 titanium and x dust. But its application would above all be for luxury resources. 

Indeed, this idea comes from the fact that at the end of the game I often get 900 pieces of a luxury resource a turn and its being sold automatically, without my having to type "999" and "ok" at each turn for each resource would make the end of the game funnier.
