Workarounds for multiout VST instrument automation with global copy?

This bug has been in Nuendo and Cubase for a long time but it’s really hitting me hard on a current project with lots of synths and automation.

That is: doing Edit / Range / Global Copy and Paste leaves any automation on non-primary tracks of multiout VST instruments unaffected. You have to manually copy them with the range tool. The additional outputs of VSTi tracks simply don’t seem to exist as far as Global Copy is concerned.

I was wondering if anyone’s figured out a workaround with this, or is manual copying really the only way?
