I suddenly see this pull request phantamanta44/ae2-fluid-crafting#18
its repository
https://github.com/123FLO321/ae2-fluid-crafting/tree/1.12-18-outputs
it use the forked PackagedAuto
https://github.com/123FLO321/PackagedAuto/tree/1.12-18-outputs

that pr seems completely ignored by miffy lol.
but anyway, you can use pack auto to make recursive patterns that can have 9+ outputs. it more like something should be done in pack auto side instead of here
