Force players to accept missions rather than reject them

This is just a rant with a suggestion that I think would make the game better.

I really like SOASE, but the mission system annoys me. I hate having to constantly reject missions. I would like to see the button say "accept" instead. Why should I have to constantly go to the diplomatic screen to reject missions I don't want. (I hardly ever accept a mission because I don't seek the Unity's favor). Why can't I simply accept the ones I want and when I ignore them they go away (similar to EU3 - where a diplomatic action is cancelled unless accepted)?
