I like the idea of the indicator being moved to the ship of origin. But I have another feature to add to that. Treat it like a damaged component on the ship, where it floats on the side of the screen that the component is relative to you, so you can easily see where it is in relation to you. This way, when your ally is saying "We could really use some help over here", the indicator is in the upper left of your screen until you look over in that direction and see it off in the distance, letting you know at a glance which way to go.
