XDCAM EX SD card file structure problem

I often freelance for the BBC regional news.

Their workflow consists of shooting on a PMW-500 (at 35 Mbps) onto SD cards via an SxS adapter.
After the shoot the SD card is inserted into a card reader and the shots appear on the FCP 7 log and transfer window. Their SD cards have a root file structure of /BPAV

When I work for them, I use a PMW-350, a Sony MEAD-SD01, and one of their SD cards. The problem is my shots don't appear in FCP's log and transfer window as the file structure is /PRIVATE/SONY/BPAV and FCP is looking for the BPAV file. I presume this file structure is being generated by the 350 when I format the card in the camera.

I know there are many ways of working round this, but I'm wondering if there's any way I can get the 350 to write the BPAV file to the root directory of the SD card so that I fit into the BBC's workflow more seamlessly.

Any ideas gratefully received...
