Gurren Lagann complete collection?

Ok, so I bought the Gurren Lagann complete collection recently. And apparently it had the televised version of episode 6 in it, (the There Are Just Some Things I Have To See episode). I want to know if there is a Gurren Lagan Complete Collection available with the other version of episode 6, (the Sit In The Hot Tub Till Your Sick episode). And if theres not a collection like that available, is there anyway to access this version on my complete collection? All answers are appreciated.
