Well, you cant move stuff in the editor, this will invalidate the lightmaps. There is no workaround. What you can do is, set all objects to be “movable” but then for every static mesh activate the option “light as if static”. Then, if you have hard offsets, move them via blueprint at runtime.
But it sounds like you are working around a problem that is wrong to begin with. What exactly is your situation and what does your scene look like that you have to move it etc? Did you check “Lighting Scenarios”? Maybe have some screenshots about what you are trying to do?
