render in place with multiple tracks with HW inserts (external fx)

I use a lot of outboard during a mix and would love to be able to use render in place to commit the outboard for MULTIPLE tracks at once. But it seems that Nuendo processes them sequentially, not simultaneously. So I have to wait for 12 real time passes of the project if I have 12 channels with external FX to render…
Am I doing something wrong? Or do any of you have a method for this?

Let me suggest a workaround. Send from HW insert channels to dummy group channels and use those as inputs on new audio tracks to (real-time) record multiple HW inserts in one go. Simply assign no output to the dummy group channels so you won’t hear HW signals twice while printing.
