Is it possible to make different IP range?

Hi,
I’m using a mikrotik and a non-mikrotik router with dd-wrt as its firmware.
My question is, is it possible to configure IP range as follow?
Main mikrotik will provide 192.168.1.0\24 so it will open ip range 192.168.1.1-192.168.1.255 right?
Now I want to make a group range of IP as follow:
wlan1 range: 192.168.1.100 - 192.168.1.199
Ether2: 192.168.1.200 - 192.168.1.254

Some devices which are connected through Ether2 have fixed IP beyond that range. Let say I have configured DVR for IP 192.168.1.20.

My main purpose is I can have fixed IP which connected through LAN port of my router, and for devices which connect to router wifi will get ip between 200-254 and it will be directed to hotspot page.

Is it possible to configure IP range like this?

It would be easier to put the different clients in entirely different networks (192.168.2.x, 192.168.3.x) and route between them.
