Open in Wavelab?

Is there a reference anywhere to exactly how Wavelab is meant to be used as a ‘round trip’ editor for files in Nuendo or Cubase?

This appears poorly documented in all manuals: on the Nuendo/Cubase side there is an ‘Open in Wavelab’ menu item & on the Wavelab side there is a non-descript ‘target’ button that sometimes updates the corresponding file in the DAW.

Is there more than this re. complete round-tripping? Presently it would seem that relatively minor file-level edits can be made & updated; on the other hand, would seem no way to commit FX from the Master section, or to use Audio Montage processing etc.

If that’s all there is, then perhaps best to stick with independent ‘pre-master’ renders.

Ah, ‘render in place’ in Wavelab, then update back to Nuendo they tell me in the Wavelab forum.
