altitude change using networked P2A

[Hilkiah 4]

Can someone advise how a step change or an altitude change is done when using a networked version of P2A (which doesn't allow you to speak to the ATC)?  

If this is not possible then I would suggest a few entries offered in the text selection area for altitude climb/descent (maybe 3 - 5 options increasing by 1000 for each one).  That way you can gradually request a different altitude up or down close to yours.

If set up correctly, you can speak to ATC in a networked installation.

However, another option is to request altitude changes using SayIt Plus (?+).  There you can enter the desired altitude and let the copilot make the request.
