Add circuits to fuse box?

Is it possible to add circuits to the in-cabin fuse box? I am going add an AC-inverter, and would rather run it on its own dedicated, fused circuit instead of splicing into another circuit. There are empty fuse slots from the front of the panel, however I'm not sure what is available from the back side (and I figured it would be worth asking if anyone knew before I break my spleen trying to look behind the panel).

Thanks in advance!
