How to set up multiple RaspberryCasts

[AbeerBPi]

Hey everyone! I tried out RaspberryCast recently and I loveeeddd it. It does everything just as I want it to, how I want it to. Now I want two of them, one upstairs and one in my living room. However, it seems the chrome extension (the only interface I have tried so far) is made to only cast to one RaspberryCast. How do I get it to control multiple different RaspberryCasts? Appreciate all help!
