Tell you what. If you do a bit of research, or just look at the charts, you'll see them. Or you can just trust me that they're there, being that I have about 50 plus years at that airfield...lol.
If you decide you want to add them, you'll need to start sourcing material anyways. This isn't like I'm saying a corner of building is off or something like that. I'm not trying to make a big deal out of this. This isn't some super-secret item that's hidden away somewhere that we're asking you to put in.
