I tried implementing this myself, but after successfully implemented the GUI part I ended up overwhelmed by the code complexity and failed making the functional part.
In essence it needs to allow usage of other locations than JPCSP\ms0 for memory stick. I attached the patch file with the work I made. The patch is compatible with r3454-3455.
