<R69>
meet all of the following criteria:
• For a single MATCH, the ROBOT shall be limited to react to a maximum of four distinct commands - either through hardware or software limitations, or a combination of the two.
• The ROBOT shall not dynamically change the recognized command set during a MATCH.
• The ROBOT may only seek out and react to permitted SIGNALING DEVICES belonging to the assigned ALLIANCE (as defined in Rule <R65>). Intentionally reacting to other SIGNALING DEVICES is prohibited.

<G01> HYBRID PERIOD - The HYBRID PERIOD is the 15-second period at the start of the
MATCH. Driver control of the ROBOT is not permitted at this time. During this period, the ROBOTS may react only to sensor inputs and commands programmed into the onboard control system. The only external signals that may be received by the ROBOT are those sent from ALLIANCE ROBOCOACHES. No external signals are permitted from any other source. The ROBOT may react to no more than four distinct external commands provided by the ROBOCOACH. All ROBOT safety rules are still applicable during the HYBRID PERIOD. The HYBRID PERIOD ends when the arena timer displays zero seconds left in the period.

I believe that it is pretty apparent that the GDC wants us to use the four commands as just that -- commands. I interpret the rules stating that any sort of command to do any one thing is permitted (eg. drive straight; turn left; or an entire autonomous mode), so that the buttons could be used to select a list of commands, however complex those commands are. However, I believe that any sort of stepping command, or combinations of buttons are not permitted.
