Granular quality

[ed_boy]

Hi all,

I'm new to modding factorio and am working on a mod that tweaks the quality mechanics, so I have a couple questions.

I can change the productivity of a specific recipe with `ChangeRecipeProductivityModifier`. Is there a similar way to change the base quality chances of a recipe? I want to be able to research a technology that will make it more likely to get higher quality items when manufacturing specific items.

Also, is there a way to unlock quality levels granularly for different items? I can see that `UnlockQualityModifier` allows me to unlock a quality level for all items, but I want to be able to get early-game items like plates and gears at high quality early on while later-game items have a more restrictive quality cap.
