setting "scratch" disks for audio and waveform data?

[nelsonmay]

I just bought and upgraded to PT 10 and I am on ML. I am using an mbox 2 and my defaut audio goes to an external esata drive.

I created a templet that I like to use for all VO sessions. When I open the templet I can save the session, but where does my raw waveforms go.

I am a Final Cut Pro/Adobe user and when you start a new session it is good to make scratch disks that aren't on the OS or in a separate folder in case you need to move the session and its elements.

Under performances is there a option to set all my waveform and waveform data to a folder of my choice on a separate hard drive?

Cheers.
