Can we have separate positions for multiple campuses?

The Campus field in the position module is an open field, which means there are no tables to setup for different campuses.  That field is intended to inform your congregants which campus the position is associated with. 

ServeWire has no way of knowing which campus a congregant (test participant) is associated with, so there is no way to know which campus position is a best fit for them.  In order to accomplish this, you will need to create a new test section as follows: 

Once you've added this section to your test per above, you can now add the campus as a qualification on the position for that campus.
