Maybe one feasible of doing it is by not letting the OS auto-mounting the disk, but instead tell Kubuntu where do you want it to be mounted, that is, as another folder inside your home directory (like in ~/Pictures/Photo).
The most straightforward way I’ve seen with a GUI is using the gnome-disk-utility (or Disks, as it is told in my Linux Mint). There you can easily edit the mount point, while still auto-mounting the disk. That is, it will be mounted as you plug it in, but you will see it in the folder you have set.
I know you are under KDE, but you can install that application, yet.
As always, with that app you can do really bad things on your disks, so you better know what you have to do before even starting
