Multi-out in standalone app

[gorangrooves]

My plugins support 8 stereo outs and work as expected in DAWs.

However, for standalone apps, I can only select a single stereo output of the interface. The interface has 8 stereo outs, so I would expect to be able to select them all and have each stereo output from the plugin go to the appropriate stereo output on the interface.

@Christoph-Hart Is this possible?
