If you own the Maximum Edition C2, can you confirm whether it allows you to create more than one account (via the in-game menu) with each account having access to the DLC?

The original DLC release only allows the purchasing account to use it, and I have DLC1 on one account and DLC2 on another and they cant be combined...

I cant find an answer to this anywhere. Thanks in advance--

(As a side note, how is the Limited Edition Bonus content handled? Is it a one-time redeemable code, or is it simply unlocked for each account you create?)
