yes, it is possible - we actually let you set very complex rules through the UI

you can click on 'advanced' when choosing the targeting conditions, and enter arbitrary rules using JSON

<https://docs.growthbook.io/app/features#conditions>

I mean what if our rule can’t be set through UI?

the feature list is just a JSON object, so you can add to it after you fetch it

technically you don't need to use our UI for the feature rules at all, the SDKs are standalone rule engines
