Multiple groupnets using the same subnet

Hello,

Could someone advise with onefs 8.x, we can setup multiple groupnets from the same network subnet ?

Our Customer intends to accommodate 2 AD domains using 2 groupnets on their isilon from the same network subnet due to fewer network resorces at DR site. As far as i tested in lab, it does't allow overlapping subnet between different groupnets. I'm wondering if this is by design and if there's a future plan for any enhancement.

iq221-1# isi network subnets modify groupnet1.subnet0 --gateway=10.32.239.1

Subnet 'subnet0' (10.32.239.0/24) overlaps with 10.32.239.0/24
