So basically, the idea will be to be able to change some block in the blueprint. I explain, Example, when i build an icanth or something like that and i don't love the red light, if i buy a new one, i will click the red light, and i can change it for a white light in the blueprint
Second exemple cause i don't think it's really clear, If i don't want the grey standard armor cause i got a red crystal one in my inventory, then i will click the grey standard armor name in the blueprint, then a list will appears whit all the armor cube and i will choose the one i want to replace it. So if it was a Grey standar armor tetra, all the tetra armor will appears in the choice. So like that you can "customize your blueprint to get stronger ship or better look for you faster then replacing all cube one by one
