@davetuck says, it's hard to figure out what the OP wants. But as *I* understand it:
Yes. Add the video like you normally would. Probably in a scene all by itself. Then create a macro in
Advanced Scene Switcher to detect when that video finishes, and stop the stream.
Adv. SS is a general-purpose if-this-do-that automation tool that can do far more than just that. You just have to understand some of the more quirky triggers if you happen to need them (media detection usually is), and build the "erector set" from there.
