[REQ] Automatic marks from stedimeter to nav map?

[Major Johnson]

I've been trying to understand manual targeting lately, watching the wernersobe videos etc, and I find I have a problem transitioning the co-ordinates from the stedimeter/TDC to the nav map. Forgive me if I'm not being clear in putting to words what I'm thinking. For example, I don't think the skipper of the boat, who is looking through the periscope and spitting out readings is going to actually make his own marks on the nav map. I would think another officer is standing there making those marks for him. So I was wondering if it would be possible for when you take a stedimeter reading, that that information could automatically appear on the nav map in the form of an X mark and maybe some blurb of info, like the time. So that when you take the next reading, another mark is there, and then you can draw the line to get the heading and continue on with your firing solution. Is this something possible within a mod??
Thanks.

Edit: Of course those marks would be subject to error if the reading was in error.
