Cloudmin KVM GPL image store path change

Hi, I'm trying to find where to change the path of the new system images store (which by default is in /var/webmin/server-manager) but I didn't have success, I've tried to find this menu described here http://www.virtualmin.com/documentation/cloudmin/vm/making-images with no success as well.

I'm using the GPL version of Cloudmin KVM, is there any way to change the path other than mounting a different volume as /var/webmin/server-manager ?

Thanks for any help in relation to this. Regards, nousa
