@kylian Well the simple answer is yes you can. In the host management page of the target computer there is a filed to identify the disk you want to send the image to.
The bit longer answer is the format of the disk is dependent on how the disk is connected to the computer. If its over a sata cable then disk 1 will be /dev/sda, disk 2 will be /dev/sdb and so on. So if you wanted to deploy to the 3rd disk on the computer you would enter /dev/sdc into that field.
