tmf files

We have several workspaces (12) in our Interplay system (02 ISIS)

When we Send to Playback a sequence, the system creates a temp directory and a tmf file. After the airspeed catch these file, they delete it.

There is a logical order where AVID choose to create  the directory? Drive us crazy, some time creates in one workspace, sometimes creates in another workspace.

There is a way to setup wich workspace I want all my tmf files to go?

thanks
