Setting timed bandwidth limits on Tomato

[Barry]

Right now I'm using a old 2013 router that's still doing just fine using TomatoUSB with the basics setup.

However now I'm looking into the possibility of setting up bandwidth limits during certain hours of the day either by GUI or a basic script.

So my main question is;
A) Is it possible to change bandwidth limits during certain hours?
B) Is it possible to do so and other clients won't notice from I assume is a service restart (eg only ~3 seconds to reboot)

Edit; So learned how to do it with the schedule cron job in tomatoUSB so if anyone finds this post heres some helpful info for the script which can act as a template (NOTE; QOS and bandwidth limiter both need to be enabled);

service qos stop

nvram set new_qoslimit_rules='
192.168.1.20-22<99999<99999<99999<99999<4<0<0
>192.168.1.3<1400<1500<200<200<3<0<0
>192.168.1.30-31<800<800<200<200<2<0<0'
nvram commit

service qos start

Edit2; Can see the changes applied but not sure what other service to restart to get them applied hmmm....
