There should be a way to have the ability to reserve an IP and still have DHCP assign the IP by mac reservation. There's no technical reason this wouldn't work and likely a feature a lot of people would love to see. The only hold back is the UI not allowing you to do so.
Ultimately, you can go to the DB and change the VM's IP in the nics table to what you want (reboot the VM and the IP change will occur). Which is not the preferred way to do so, but ultimately that functionality from the UI would be ideal. Even going as far as intergrating IPAM functionality into the product would be ideal.
