MikroTik RouterBoard DHCP .. Guest connection

hi all
thanks all for support

kindly we have a RB1100AHX2, we configured our DHCP server with leases and lock it on our clients computers MAC addresses in our company.

we have a different WiFi access points in all the building, we need to figure a way for our guests that like a hotspot page request a username and password then they can access the internet for 1 day, how can we do that?

i mean any MAC address which is not listed in our leases setting.

your support is highly appreciated.
