Hello,
I believe Factory Planner has this feature and it would be very useful.
When you're looking at a production line's "summary" button, and it makes a huge list of buildings & modules that are the sum-total of everything you need? It would be really nice if there was a button which would create a blueprint of a constant-combinator with all of these buildings/modules already put into the constant combinator.
This way you could easily plug that into a requester chest or buffer chest to create a system that automatically gets everything together for you. Or you could plug it into your "automall" system to start crafting everything you will need, etc. There are a variety of reasons you might want all the buildings for a production block as signals, and this feature would help us accomplish that in one click, rather than needing to manually add a dozen or more buildings to our "shopping list"
Thank you for considering this feature!
