Launch a new session from rdweb or remote app rdp file

i need force published application run new terminal session every time icon clicked. have reason , if want tell me why should not not answer looking :)

let me see if can explain:

first have setting restrict each user single session turned off. can launch desktop session remote desktop minimize and launch another one and login same name , 2 sessions pc same terminal server logged in same user name , works fine. if create published application click , click again takes me first session running , not open new session need.  it great if can done on per application bases because i really only need 1 app important 1 if can system wide setting ok.

i think you can tell remoteapp not adding following line rdp file:
disableconnectionsharing:i:1

should work rdweb far can tell.
