Default Change USB mount folder

Hi, I've just received my meenova sd card reader and it works perfect with my phone (although root is needed). I can mount the sd card with stickmount app but the problem is that it creates the directory in /0/usbStorage/sda and I need it to be in /0/usbStorage (without that "sda" subfolder). Is there a way to change that or another app that allows to do that? Thanks.
