Restrict certain apps to only use Cellular (not wi-fi)

[resarfekim]

I know you can restrict a particular apps from using cellular data. But I'd like to do the opposite...

Is there a way to force an app to ONLY use cellular data, and not the wi-fi connection?

You could use AFWall+ but you need root for that.

Thanks. I'll keep searching for a non-root method, for the app I'm trying to block is one of those annoying won't-run-when-rooted apps...
