Way to invoke multiple imsi msisdn in sgnsemu

[anish achenkunju]

Hi All,
 
Wondering if there is a way to create pdp request for multple imsi or msisdn. 
 
Currently there is an option to emulate more than one pdp context, can we do 
the same for different imsi's or msisdn via sgsnemu as an input to sgsnemu.conf 
file?
 
Thank you in advance.
