I have 5 Toshiba DKT2010-SD which all have their own 2-digit speed dial codes (11->16).

I would like to program some of the buttons on the phone to automatically dial a specific 2digit code rather than having to remember which code to enter.

In other words, I would like to be able to press the button labeled "SD1" and have it automatically call station #11.

So far all I have been able to find online and in the manual is information to set full phone numbers to shortened speed dial numbers (page 53 of the manual). I want to simplify it further since I only ever really call a few numbers but have difficulty remembering which one goes where.

Does anyone here know how to do this or if it is even possible?
