Mac address filtering

I am thinking of replacing two Linksys E2000 WiFi/Wired routers that connect to a Verizon Fios Cable Modem/router with the RB50 system.  I currently keep a list of acceptable MAC addresses in the security table of the Linksys rounters as an additional security measure and just add/delete an address as needed.  I didn't see this capability mentioned on the website or elsewhere.  Can anyone confirm if the RB50 will allow me to continue to use this added security measure?  Thanks!
