The button Change similar tiles , available in the Components window when you apply Covering materials, is automatically switched on when you drag&drop a dynamic pattern in the scene.
As this is the standard way to apply tiles in the slots available within the dynamic pattern, you are sure you're in the right mode when applying a new dynamic pattern.
Remember to switch this button on every time you need to replace a tile from within a dynamic pattern.
