AVON UK Can I 'back order ' from the previous campagine brochure?

I have just become an Avon rep this week and my sales manager gave me campaign 16 and 17 brochures. It says online that campaign 17 orders are due by 10th November. I am just wondering whether I can allow customers to order from brochure 16 this week and submit the order along with my others from brochure 17? I didn't want to hand out the campaign 16 books if it was going to be difficult to order from them. Sorry for asking what may be a silly question but it's all new to me at the moment. Thank you for your help! x
