TL;DR
Add the ability to put deconstruction and upgrade planer in bluerpint book and the library.Why ?
When I expand into bitters I'm using a set of blueprint that place rail and station for my artillary and I also have upgrade and deconstruction planer to move it forward in steps without removing the rails, power pool, signal, etc.The probleme is that it's clutering my inventory so when I'm not expending and I need inventory space I need to destroy them and redo them each time I start expanding.
So if I was able to just put them in the book with my other expansion blueprint I could just have them with the rest of my expansion blueprint.
