Custom Playbooks?

Hi everyone,

Relating to the custom playbooks, can you add plays from a different team into your teams' playbook? From what I saw with a minimal tinkering with this is that you can only add or remove your own teams playbook. If anybody has an answer on this please share.|||Yes you can, but it's confusing.

One screen (you sort through 3 with the bumpers) has a series of checkmarks beside each play. You can use the triggers (LT and RT on 360) to change the formation and set. Add a play by placing a checkmark beside it to a formation you don't have and it will show up in your playbook. Mind you, the new formation will have its own screen on the playcall menu and you can't add any common sets below it, but it will be there.|||Thought I'd try this instead of starting a new thread. Where can I find empty backfield in custom playbooks? I can't find it to save my life.
