track/fixed

how come i can only enter free warp mode and put down warp tabs in track tempo mode, and not fixed. I have to go into the tempo map and set tempo, then free warp a audio track to grid? In reaper i would just tab to trans. How do i go about doing this in cubase 6. and also is there a way to drop warp tabs in the audio part editor, or do i have to go into the sample editor, the audio part editor looks so much cleaner.

on a side note, wow, variaudio in the sample editor!!! sounds amazing
