Multiple IP Range in port forwarding in FreshTomato

Hi forks,

I want to forward 1 port from internet to a IP in my LAN, but the source I want to limit only for some IP range, like 1.2.3.0/24 and 2.3.4.0/24.
I tried with 1.2.3.0/24,2.3.4.0/24 or 1.2.3.0/24;2.3.4.0/24, but it won't let me save that. If I create multiple rules for that port, it only apply the first one rule.
Is there any way to archive that.
Thanks a lot.
