Change some tiles only (multiple tiles replacement)

If you want to change some tiles only, from the Navigation window click the right mouse button over one of the tiles you want to change, and select command Change tile->Multiple selection. Proceed selecting one by one the tiles you want to change (left image), with the left mouse button; click the right mouse button when you want to stop selection. Choose the new tile to replace the old one with, and finally leave the check on Single tile when you’ll approach the Replacement type mask. In fact, you want the Application to replace just the tiles you have manually selected one by one. In the left image you can see the result of the Multiple selection replacement procedure.
