MMS directly with shortcut

[cicijay]

I have been able to succesfully create shortcuts to automatically create a text message.

for example: \windows\tmail.exe -service "SMS" -to "40404" will open up a text message already addressed to 40404.

I am trying to do the same with Pix messaging using MMS.
With my Verizon XV6900 I try:
\windows\tmail.exe -service "MMS" -to "1234567890"
but it automatically opens the FLIX message by default since Verizon views FLIX and PIX MMS message differently. Any way to get it to go directly to PIX message?
