Multiple Brands Using One Social Sourcing Site

Summary

Our company has two distinct brands - one in the US and one in Canada - what is the best way to differentiate the jobs on the site?

We are currently live on Social Sourcing/Sourcing Center in the US and are planning to roll it out to our Canadian division. We have two social sourcing sites set up - one with the US name/logo and the other with Canada.  However, we have been told that both sites will contain the same jobs - as there is technically only one social sourcing database. Has anyone had this issue of two brands using the same site and, if so, how did you differentiate your jobs in a clear way?
