Is there a way to add another category sidebox? I have "Home Equipment" and "Commercial Equipment", and I'm finding that it would be best to make them as separate as possible. Right now I have Commercial Equipment as a main category near the bottom of the rest, and it works as long as I link to it elsewhere on the site to make it more obvious, but it isn't ideal. Making two parent categories for Home and Commercial would waste space for category name lengths, because everything would be a subcategory of Home or Commercial.

Many Commercial products also have linked copies in Home, and it would need to stay that way.

Is this feasible?
