Nice idea!
But as you stated yourself, this idea has been made already (several times) and splitting up votes between several very similar ideas, harms more as it helps, as devs will implement feature with most votes.
So I suggest, to combine the original feature vote idea [Implemented] Airport Planning Tool with your addition of “build blueprint by switch”, so we have one better feature, which collects all the votes…
In the end devs will decide if they can fully implement, or only partially.
