Picking up placed blocks?

I am new entirely to forum posting, so go easy on me. This may have already been answered, but I was playing Rising World and I am slightly annoyed at the fact that you can't pick up the items that you place, such as the work bench and what not. Is there a way to not lose these when you destroy them or is this still not a part of the game? If not then what ever, I can deal with it for the time being.
