Is there a way to change the default filename prefix?

Probably a long-shot, but with multiple 0806 µSD cards connected to a PC, the file names are identical across all cameras. It would be a god-send to have each camera save each file with a unique prefix.

For example, instead of all of them being "", have one camera be "", with the next being "" and so on.

It appears that the text file in the root directory of each card contains the file name of the last file written - presumably to tell the camera what the next file name/number should be. I change it to something unique, but with the first write to the card by the camera, it reverted back to the ambr prefix.
