 - **Join Mesh**: Merges multiple `SlicingObject` instances into one.
 - **Join Paths**: Combines multiple `SlicePaths`. Supports Sequential or Interleaved modes.
 - **Join Gcode**: Concatenates multiple G-code strings.
+- **Join Overrides**: Sequentially merges multiple override dictionaries. Later inputs overwrite earlier ones for matching keys.
 - **Integer Math**: Simple integer operations (Add, Multiply, etc.).
