2 ip pools in Mikrotik, how to do it?

Question

DHCP

Task. There are 70 pcs. You need to make sure that 35 PCs take ip on the 99.99.99.0/24 subnet and 35 PCs on the 123.123.123.0/24 subnet. Mikrotik with 2 network cards is used as a server. How to implement it?
In other words, to make it clearer what I want.
Maybe by setting dhcp to one dns, you can specify this dns PC so that it pulls the subnet ip pool from the dhcp with which this dns is connected.
If it is not clear, here is an example
of Dns 99.99.99.99
Dhcp 99.99.99.0/24
On the PC, you specify dns 99.99.99.99 and you get ip from the pool 99.99.99.99
And the same with another
Dns 123. 123.123. 123
Dhcp 123.123.123.0/24 Specify
dns 123.123.123.0 on the PC and get ip from this pool.
Mikrotik is the server

Answer 1

2 DHCP servers with 2 pools. First, we create pools in "IP->Pool", then - in "IP->DHCP Server" we create a server, and the pool and interface are also selected there.
