DHCP Relay with additional addresses

we have a asg version 8.306. 

for address distribution we have a dhcp server on one interface (type ethernet-vlan) and configured the dhcp relay service on the astaro. for some other interfaces (vlans) this is working properly. 

on one interface (vlan) there are additional networks connected, the configuration is a following:

interface: 10.199.0.1/16
additional1: 10.142.0.1/16
additional2: 10.144.0.1/16
additional3: 10.160.0.1/16

now we want to use the dhcp relay service also in all of these networks. however, in the interface list of the relay interfaces you can only add real interfaces, not the virtual ones from the additional addresses. this leads to forwarded dhcp requests with the forwarding ip of 10.199.0.1 and the result, the dhcp server doesn't find the host entries of the hosts in the other networks because they have configured fixed addresses in these nets.
