Please allow setting hostname from the qemu parameters in GUI

Happy new year!
According to the
https://wiki.qemu.org/Documentation/Networking#Advanced_user_networking_options
It is possible to define the hostname from qemu -netdev argument. It would very useful to be able set it up in GUI especially when cloning an image and running multiple copies of it with a different hostname. If this feature already exists and I missed that I apologize and kindly ask a reference to the documentation.
