Inaccurate Transport AI Drops

I've been trying to learn more about the Transport AI recently, and I've noticed something a little agitating. When
moving units via a ferry route or the Que Embark command, they drop in a Very large area. I can see how that would be useful if I'm moving a very large number of units, but with a smaller force, it means I have to be very careful with where I tell them to land.

Some screenshots of the area the units are dropping in.

Is there any way to have the units land in a smaller area with either of those commands or do I have to do drops like this manually?

There isn't a way to with the Ferry command or Queue Embark. With other commands, you can area select, and that's how I got the bottom picture.
