LoadBalance Info on Wyse Management Suite

Hello,
We are running WMS 1.3.0 40983 and I have a question about it.
We have a new broker and, to connect to it, we have to add this line on a .rdp file :
loadbalanceinfo:s:tsv://MS Terminal Services Plugin.1.Bureau

Do you know where can I add this line to a wyse client ?
If I only add the name of our broker, it doesn't work (because we need the loadbalance info)

Thanks for your help,
