I would love to be able to change an existing assemblers recipe and module slots via a blueprint. I want to make a blueprint of an assembler, smelters, refinery or what have you, with the modules and just click and drag over existing machines and be able to quickly change out the modules via bots. For an example, this would help when I want to replace modules on smelting setup from two speed to a speed and a productivity so I don't have to click on each smelter and replace the module.

Me to. Let the bots work for you.

Can we change it so we can upgrade assemblers via blueprints at least. Currently If I want to upgrade then I have to deconstruct the assemblers and build it again. I want to Shift click and one bot picks up assembler and another bot place the new assembler down, just like using bots to build rail and removing trees and rocks. I can only find a mod that changes the blueprint to higher assemblers but I don't see one that will replace existing assemblers.
If the Modules can be replaced via the above method that would be great.

How hard would it be to write a mod that would upgrade a building via bot just like a player placing a higher level building on top will upgrade it?
