It is possible, but at that point, you would want to write the code in C. I don't write in C as I'm not trained enough in it to do so. Adding SD compatibility would easily quadruple the length of the code, not even mentioning SDHC. It's not even the SD function calls that will make the code much more complex, it's handling the FAT/FAT32 file system, it's a nightmare.
You can however quickly change the location in the NAND file system where it's stored without any coding knowledge
Change the path in between the quotation marks, re-compile.

Code:
.string "/shared2/report.txt"
