Craftable houses MOD

So I currently working on a mod in which you can craft a prefabricated FOB. So for instance you have your main base set up in Viking bay and wanted just a small outpost near a taming pen where golems spawn on Ragnarok. You can go to the crafting bench craft a FOB and then can just place it down saving you the time of have to build it yourself. Is there any way you can make a structure within the play mode and then select and save? Or will I have to create it in the components tab and have to live with it being one single structure instead of the individual structures that make up the building
