very possible, just use a variable to set path, window name,
TTS holds what RR will say when loading the screen..
APPPATH holds the path for the selected application..
APPNAME holds the applications window name..
of course you need to set the variables value first. depending in how you will select your applications you will set the values, maybe from a custom list?.
using a custom list:
you must repeat this step for each application.
and the button code for run the selected application would be like this.
try it, i think it will work.
