"Accept all" would indeed make the gathering missions go faster..
Even be nicer to put them separate automatically. So you can choose to see all faction missions or only recover code missions/ s&d missions.
In another game I play, they just make an options tab where you can select what you want to see and how.
To personalize your game experience a bit more.
/signed to add BOTH the accept all and the checkboxes OR BOTH the accept all and the accept all S&D and accept all recover codes
