Setting some MM7 parameters on the fly

 hi,

Is there a way to set the following parameters on the fly for the Parlay X MMS sendMessage API mm7 plugin?

Understand for parlay X mms, there's only a senderaddress and it might be possible that this is alphanumeric.  Due to my constraint of the mmsc, i need to have different set of http authentication (vasid and password) for different senderaddress.

I also need to set differently the following values in the mm7 request submitted to mmsc.

<VASPID>1000</VASPID>\

<VASID>1000</VASID>

<SenderAddress>Testing</SenderAddress>

Thus I'm wondering if the above 4 parameters (include password) can be set on the fly via interceptors or x parameters. Any advise. tks
