Audibles

This isnt a question of what I should use. But 2 other questions

I know you can set your audibles outside of the game and do it that way, but is there a way to use another PB and set audibles do it so I dont have to pause the game and do it.

Also, Besides with a hurry up offense, does anyone find audibles to be worth it? I find that I dont have enough time usually with the run off on the clock

Another playbook as in a different teams playbook, or as in have 2 playbooks saved?

And it can be useful if you come out in a run and they are stacked, and you want to change to like a screen or something, rather than the default run plays or whatever.

Audibles can be very helpful..Learn to read the coverage

I know they can be helpful I just meant..cant people get them out in time...BUT..for instance, when you go under the main menu and you go to change audibles that way, it saves it. Im using the cowboys and it comes up as Wade by default, can I change that, because i cant figure out how. I want my book to come up as a different one
