storing PIN with voicemail speed dial

[pavemen]

Stock Sprint WM6.5 ROM.

How can I get the voice mail speed dial entry (Key 1) to keep the voice mail PIN, associated pauses and # key press? I was able to do it on my previous Palm devices, but when I try to edit the "1" key speed dial assignment, it takes me to the phone options screen. I append ",,,,XXXX#" to the Voice Mail Number but it does not accept it.
