I am currently playing a game with the castra mod, where you want to not kill spawners, but the enemies that come out of them. Hence I would love an option to ignore a certain target. Currently this already works by creating a priority list with all valid targets except the spawner. And enabling only fire at priorized targets.

This could also be fun in the base game by incentivising leaving spawners alive, but cauterized to avoid farspread pollution.

If it already works, then why make a suggestion? And I have already seen it used on biter spawners.

I think he's asking for the QoL feature of having the option for the filters to toggle between a whitelist and blacklist, much like you see on inserters.

IMO, it's bizarre this feature doesn't already exist on other entities you can set filters for.
