VideoStorm Maximum Sources and Saved Multidisplays

[ControllAll]

I'm just getting a VideoStorm system setup and have a few questions. It seems like the C4 driver is setup for 16 sources. Can this be changed (increased)? I have a number of IP cameras that together with traditional video sources puts me over 16, so I can't bring up sources over 16 from C4.

Also, with all the IP cameras, I rarely look at them individually, and instead have several multidisplays that work for me. What's the best way to call these up via C4? Right now I use a disabled Source channel, and have programming that sets up the multidisplay when that source is called upon. This seems a bit clunky, and also uses up more channels (thus making the 16 channel limit in C4 worse).

 

Thanks!
