Nuendo's "Open In Wavelab" doesn't open 5.1-files

In plain language can someone tell me exactly what they want WL to do with multichannel files? It seems that it can handle multichannel files in the Montage but are people asking for it to work with multichannel files in the edit window? If so doesn’t that mean that WL would become a multitrack DAW? I am somewhat confused as to what users really want. Thanks in advance!
