Stereo Tool

i am having someone make an applet for my DJ's that will give them weather, traffic, and news stats as well as notify them of requests, and i want them to click a button in that applet when they are announcing the traffic that will trip the RDS TA button and un trip it when they click it again i thought maybe there's some kind of way to do it through the web interface, but i can't seem to find a URL or anything behind the button in the web interface is there any way to do what i'm trying to do without having them controlling ST directly?

Options:
1. Use a file and enable Parameter Scheduling http://help.stereotool.com/7.60/scheduler.shtml
2. Use the web interface
