question on published apps in citrix forcing to run on same server

We run 6.5 xenapp we have 8 2008 r2 servers running our farm. What we would like to do is force all MS office apps to run on the same server per user. For instance a user opens outlook and it opens on server 1 if that user opens one note, excel or word we want it to open on the same server (server 1) their outlook is running on. Is this possible?
