TL;DR
Add "Ligistic update planner" tool that will allow bulk-change combinator signals same way as update planner can change entities.What ?
Imagine you created combinator contraption that computes whatever u need and you want to do the same for another signal ...currently you need top copy-paste your contraption and manually change signal with another (= 4+ click on each combinator)
Planner could work simillar to update planner but instead of items it would swap signals; it could also have switches, that would specify:
- apply to : arithmetic c., decider c., constant c., inserter, ... (anything that can have condition)
- change signal: left input, right input, output
It would probably need to ignore Everithing/Anything/Each signals because theyre special.
Given change could be done via logistic bot (immersion; not make it like cheat) as construction bots do with items.
