Adv Collections - Setting up payment reminder before due date

We have implemented Adv Collections in our US operations and the 1st Dunning letter goes on the 1st day when the account has turned over due, i..e, when the aging before 1-30 days.

We are now in the process of implementing the same in our Canada OU, but the business requires that the 1st dunning to be sent 10 days before the account is actually due. It is like sending a payment reminder 10 days before the account due date and in fact not a dunning letter.

Is it possible to generate such Payment reminder from Adv. Collections If yes, can you explain the steps.
