I noticed that in a game I played earlier today that after researching charged missiles my ships would all come out automatically using that ability in battle. To turn it off for all of my units I had to turn it off for each one individually. Is something wrong here?

I have two questions:
1) Is there a setting I am missing so that my units by default don't autouse their abilities?
2) Can I change the autouse of abilities on a group level instead of individual level?

Thanks...
