Pattern matching exclude

I would like to setup sources parameter in Error DAT in such way, that everything is included, except some specific paths like /sys/* and /ui/* (which should be excluded to avoid TD specific warnings and errors). I am guessing it isn’t possible based on pattern matching logic explained here:
I just wanted to ask whether I am not missing some new way to do that? If not, I have been thinking that maybe using exclamation mark for exclusions (using AND logic) would be a good option for the future. In such case one could specify sources like this: * !/sys/* !/ui/*.
