It is possibile to to configure multiple flat network based on vlan ranges in Neutron/Havana ?

Now, I have:

[OVS]
network_vlan_ranges=physnet1,physnet2:1217:1223
integration_bridge=br-int
tenant_network_type=vlan
bridge_mappings=physnet1:br-ex,physnet2:br-prv

It is working, but i don't want to user can create a lot of networks. I want to user or admin of tenant cloud create only one flat network and other admin of other tenant can create only one flat network too with different vlan id.

I want also to use physical router for all flat networks

The best solution it would be to use nova-network with vlan-manager but it is depreceted and I want use neutron to do this.

Sorry for my english ;/
