Using Crave on OptikTV with existing account

Just Moved In
Hi. Does anyone know how to set up Crave on OptikTV with an existing account? I don't want to set up a new account, just use an existing account.
Thanks in advance!

I had the same question, and apparently you can only set this up with a new account not existing.  Hopefully Telus will improve this for all of us that are currently customers.
