Anything like beatdetective for sx???

I tried using the tutorial to make a tempo track out of drums not played to a tempo track and I got right up to the last step and I dont see the "insert multiple tempi" button that is supposedly in the menu when you right click on selected midi. Im using Nuendo 3. Can someone explain how to make a tempo track out of drums that aren't played to a tempo track?
 
Here's something I tried today, it's not ideal but it works.

The trick to use hitpoints on multitrack stuff is to create a surround channel (you can have up to 12 track with a 10.2 surround bus), route each track to it's own channel from the surround bus, export mixdown.
Import the surround file on a surround track, edit it with the hitpoint, timewarp...whatever you want to use, bounce.
Reimport the bounced surround file you just created, check split file...you're back with your edited mono tracks.
