Select Target sound

[angelwarrior]

Hello guys,

I am creating "Nuke" ability and i would like to ask.
When i am clicking on an ability(based on flame strike) and i see Selection circle and yellow text Select target...is there some possibility that game would play some sound in that moment? I want to have something like in other strategy games where when you click on ability game announcer says "Select target" .

I tried to use triggers for begins casting, starts effect etc but no joy.

Thanks
