WiFi - Smart Network Switch - Network Exceptions - How do I add them?

[mrmadcat]

So this is really bugging me and I can't see anyone else talking about it anywhere - so I assume I'm just missing something! Any help will be much appreciated!

I like the idea of the smart network switch feature. and the aggressive mode. i have a good amount of data but not unlimited. so if there is good wifi - i'd like to use it. if it's even a little bit flakey though like in a shopping centre as i walk about - drop back to the data connection please. but at home - where i have fibre - i'd like it to always stay on the wifi. i have chromecasts etc too so it's easier.

so they added a network exceptions feature - great! but how do i add exceptions??? i can't find it anywhere in any settings!

im on the latest OS, all updates, etc. but i've always seen this issue.

anyone know?

cheers
