In case you want to save in the internal library the dynamic panel created by the Application when you drag&drop tiles over the wall, you can click the button you see in the next image (the one with the red square around it, tool tipped with Save as panel in the Application).
By doing this you will find the panel in the Components window, so that next time you need to tile the same way you just need to get to the panels section, and drag&drop it to the walls. This will lead you to the same laying situation, saving a lot of clicks/time. Be careful of typing the correct information while saving the panel, as they will be important when searching the panel you want/need in the Components window.
