Can I import a Key Command set from Cubase?

I’ve moved to Nuendo 5.5.5 from Cubase 5 and would like to have access to the keyboard shortcuts I had saved in Cubase (as an XML file).

When I try to import the XML file into Nuendo, the XML file is greyed out. I had assumed that this was because Cubase and Nuendo have different menus and shortcuts and that importing these isn’t possible.

Is there anyway to do this?
