[Koha] Serials in multi-branch libraries

Since upgrade time is approaching, we're re-evaluating possible use of Koha's Serials module to manage our magazine subscriptions. Right off the bat I'm confused about something: How do you handle a subscription if it is expected that you'll receive X copies of each issue? If I enter a serial record for Time Magazine, I need to tell Koha that we'll get 7 copies of the new issue each week. Can Koha do that?
