Setting The Gateway Within DHCP Or Multiple DHCP Ranges

Peplink 580, FW 6.2.2

Hello all,
At a client we recently had to increase the size of a LAN from 192.168.10.0/23 to 192.168.8.0/22 to accommodate growth in an organization. The issue we ran into is that our original gateway of 192.168.10.1 fell inside the new DHCP range of the /22 network and thus the Peplink would not let us keep that gateway address. Needless to say, a lot of time was spent updating statically configured devices to point to a new gateway over the weekend.

My question is : Is it possible to have multiple DHCP pools within a single LAN network? In the case described above, something like:
Gateway : 192.168.10.1
Subnet Mask : 255.255.252.0
DHCP Range 1 : 192.168.8.100-192.168.9.254
DHCP Range 2 : 192.168.10.100-192.168.11.254

I may be missing something, but I’m not able to see a way of doing this like I’ve been able to on some other network devices. It’s something I would expect from this caliber of device but perhaps it’s just not possible (yet). I’d like to make this a feature request if it isn’t since it comes up from time to time and allows us to be more nimble in production environments when sudden changes need to be made without interrupting connectivity.
