Well, you just add routes to these subnets with their addresses as a gateway 
you means
/ip route add dst-address=200.1.20.16/29 gateway=192.168.1
/ip route add dst-address=200.1.20.24/29 gateway=192.168.5

Almost:
/ip route add dst-address=200.1.20.16/29 gateway=192.168.XX.2
/ip route add dst-address=200.1.20.24/29 gateway=192.168.XX.6
