waveform preview in video sequence editor

Hi, I have a quick question.

Is it possible to have a preview of a loaded audio file within the sequence editor (something like a waveform) in blender 2.5?

thanks

You can see the audio waveform on the seq strip if you load the audio into RAM.

thanks! That works! even with an aif file. Just had to check the cache checkbox in the import dialog.
