Portfolio plugin with custom slugs?

Is there a portfolioplugin that allows custom slugs? Certain content i need to display would look best if done via portfolio style plugins, but the problem is most of them don’t allow custom slugs, or if they do they allow just one.

For instance, I need one plugin that would allow me to have my pages with url’s like this – like normal pages, without portfolio’s own slug appearing anywhere.

Buildings

• House
• Garage

Animals

• My-dog
• My-cat

/buildings/house
/buildings/garage
/animals/my-dog
/animals/my-cat

Does anyone know of a plugin that works like that? It doesn’t have to be portfolio as such, just a plugin that would allow me to display part of the content in a flashy way.
