Multiple Servers with XX-Client

Hello I'm currently running the XX-Client_2.4.162.982 with a VS9000, with one server. If I wanted to add additional servers, is it as simple as adding the others directly below the first one or is there additional info needed in the config file?

I know with RQ and Linux I had to add the following to list additional servers after the initial server, "card_server_url_0" and "card_server_url_1" would allow me three in total.

I can't seem to find the info I need to add additional servers for what I'm running now. Thanks in advance.
