Design Modular/Blueprint Factories

I often design my factories breaking them into modules, and if compact enough can create them in-game as blueprints. I’d like to be able to design a “Modular Factory”, and then use that factory in-game in the main production.

The inputs wouldn’t come from the save as such when building the module.

For example:

• Design a modular Turbofuel factory making 120/min

• Add 2 of these to the Save, producing 240/min

• Later on, increase the number to 6, producing 720/min

• Edit (duplicate?) the modular factory to now produce 200/min

• Replace old version in the save with the new version to produce 1200/min
