Question about Potty training please?

Hi…

i will be away for school 5 x a week for 7 hours..
i know that a pup cant hold their bladder that long.. its coz i want the pup to pee outside where his 'toilet' is.. will putting another 'toilet' in the pups crate confuse the puppy?

if it will confuse the pup. do you know any other way?
