Hello,
Is there any way to specify more than one value for ADDRESS per service ?
For example, i have to restrict ssh access to xxx.xxx.xxx.xxx/28 and yyy.yyy.yyy.yyy/32 network addresses without using firewall features ..
You can only make it with firewall rules. But you cann’t make the same thing for /ip accounting 
Well,
then lets move topic to feature request stage
