The challenge is to join two buildings together.

If copying "building pieces" to another building via "add to building" attempting to place using (X) Advanced Move, cancels add to building (even if that toolltip was under mouse when advanced move was selected).

Maybe a known issue but a limitation, flagged, as building pieces copied to existing building land on an offset grid without precise placement, made more difficult without advanced move.

Steps to Reproduce

Two separate buildings, containing multiple pieces, can you add one to the other? The answer is yes, with care.

Select the building you want to copy, edit the building. Select all the individual pieces (use multi selection box or ctrl) , use the copy option in the menu and then .. done. These PIECES are now in clipboard.

Make sure add to building option is ticked (lower right of screen) and hover over the destination building, it should say add to building x, in a tooltip near your mouse. Here the game is limited .. if you click to drop, the new pieces will add to the building wherever they happen to be and worse will generate a new grid offest and that doesn't fit with the destination building (that's bad, so devs please take note). Using x advanced move won't allow you to add to building either (also bad). However, if you line the pieces up by eye, as long as the add to building tool tip is active the new pieces will join the destination building when you click to drop, so ...

I tested with a couple of round walls, to make a perfect circle .. to help myself I built a couple of foundation stones, under the ground on the destination building beforehand so no matter where I hovered with the new pieces, the tooltip (add to building) was showing .as some part of the destination building was always under the mouse while I concentrated on getting the pieces lined up. It worked, ended up with all the pieces part of a single building.

I don't think you could do this with a blueprint directly from the blueprint menu but as long as the blueprint is one building, you could drop it down at random, go in edit, select the pieces, copy, done and then copy them down (as close as you can by eye) to a destination building.

Hopefully a couple of devs might spot this thread and look at making it possible to add to building when using advanced move and / or look at reading the destination grid when dropping building pieces to it because then it would work much better but you can do it, at a pinch.
