uMatrix gives me the ability to select on a domain and subdomain level where to block or allow script and other page elements using its matrix interface.

If this is possible to do in uBlock Origin, I don't know how.

AFAIK, uBO does not have a similar matrix-like interface. So if the equivalent control is possible somehow, it must be hidden further down in its interface, which makes it much less convenient for me than the simple matrix that's behind a single mouse click for me in uMatrix.

I'd love to learn how uBO can be used like uMatrix, if that's possible. There's no need for both extensions if uBO can do it all, but as far as I know it can't.
