IP range with nft-qos

Hello
In webgui for luci-app-nft-qos I cannot find option to add ip range to limit bandwidth, I want to limit bandwidth with IP range i.e: 192.168.1.50-100 limited with 200kB/s for Download/Upload, and other ip range for more or less bandwidth, any hint about how to solve this problem?
Thanks

up
anyone?

No option to do ranges AFAICT.
