@steve6248 The MCP altitude can be set using the SELECT ALTITUDE BUG assignment followed by the PLUS or MINUS assignment. An issue has been fixed in v1.3 that required you to manually disengage and then reengage ALT ARM after making any altitude selection change using that assignment.

INCREASE/DECREASE AUTOPILOT REFERENCE ALTITUDE will also be supported with the release of the v1.3 update.

SELECT AP PITCH HOLD REFERENCE and INCREASE/DECREASE AP PITCH HOLD REFERENCE are already supported for controlling the autopilot pitch selector. Although you won't see the selector move, the selected pitch value will change.
