Different Levels for Different Domains

I'm new to working with Pro Sites and am currently setting it up. Our particular situation is that we have multiple domains running on the same install of WP using the Multi-Domains plugin. domainA.com needs to have it's own Pro Site Levels, while domainB.com will have entirely different levels from domainA.com.

Is this functionality available or does this require multiple installs of WP and Pro Sites? If it's possible, could you point me down the right path for making this happen? Thanks!
