Hacking running more than one micro sc card with sky3ds?

[microbytemob]

i was wondering if anyone can help me i recently purchased a sky3ds card for my son which runs flawless , but seen as diskwriter V106b5 only allows you to write 31 roms to card ,i have a 32gd sd card at mo i was wondering if it was possible to use a second or third micro sdcard with the sky3ds instead of deleteing games & adding , i thought it would be easier just to have rest of his roms collection on different sd cards many thx in advance
