Ordinate Dim. Dim to opssit side and stayed link without breaking aliment

Ok, I have the block. I placed my zero (Ordinate dim) on the right side along with other dimens. Now I need to place some on the left side of block. I want them to stay linked to the right side. Normally I break link and dragging them over, pain in the butt. Some meant say create another "0" and hide it. Now what happens if move the zero 0" on the right side??? I thought at one time I saw something about this, maybe not
