Noob question: resolve to static hosts using hostnames

[yds]

I have a bunch of machines on my network that I have setup with static IP's on each machine.  I would like to be able to access them by typing their hostnames in my browser.  eg: I have sabnzbd running on 192.168.2.5.   Would like to type "sabnzbd/" in the browser to go directly to it.  I know if sabnzbd was assigned IP by DHCP, it would work.  But how do I set pfSense to know the names of my static machines?  Do I enter them manually in the "DHCP Static Mappings for this interface." part of the DHCP server settings?

You have Hostoverrides in "Services: Unbound DNS: Overrides" and "Services: Dnsmasq DNS: Settings"
