Multiple output audio plugins?

Is there any way to use VST audio plugins that have multiple outputs? VST Instruments can do this but I don’t see a way to set up audio plugins with multiple outputs.

I was hoping to use the rs-met Crossover plugin to create my own multiband expander but it appears it is not possible in Cubase 6. When I insert the Crossover plugin no new connections or mixer channels show up. (It appears that Cubase does not recognize Steinberg’s own multi-output VST spec!)

Cubase should have a VST send effects rack (like it used to) that works the same way as the VST Instrument rack with selectable multiple outputs, etc., but it appears it doesn’t.

Any workarounds for this?
