Make 2 crafts track each other

[REAPER7]

If I set a docking port as target and turn SAS on target tracking, then go to orient the other craft to orient and come back the first one goes back to the default SAS mode.

Can we have the SAS working on both and track each other so we just have to align 1 craft instead of going back and forth?

Once the two crafts are aligned isn't it just a simple matter of moving forward until the docking ports touch? It sounds like you are making this more complicated than it is.

Craft A should be completely still, not rotating or moving in any way, then you go to craft B, orient to the docking port and make the connection. Not sure why you are constantly switching back and forth?

As far as the change you're requesting I don't think it's possible as the game only allows you to control one vessel at a time, and I'd wager that's a pretty "hard-coded" limitation. I think someone has a mod that let's you remotely control another craft...can't think of the name though.

The way the system works is already exactly aligning one vessel to the other. What you're describing is dynamic tracking, which is not the same thing as aligning - in your frame of reference, both vessels are changing orientation to try to follow the motion of the other, which would be a really, REALLY inefficient way to dock.

But there is good news: to me it sounds like you're cutting a few corners in docking. One key step is to kill relative velocity. To do this:

Get your ships close together, within about 1-200m,
Click on the speed display on the navball until it says Target (if you haven't already).
Burn retrograde until your velocity 0m/s.

Now your ships are almost completely still relative to each other. If they're both smallish crafts, u can just use your SAS align-to-target and then thrust one gently towards the other, or if u're docking a small ship to a big station, it will be much safer and easier to manoeuvre the smaller ship around to the docking port and use translation (thrusting past rather than towards) to align to the docking ring.

Edit: try this guide for a step by step guide to docking without SAS alignment.

Mechjeb can control the other craft and can be set to point towards the ship you controls as long as both are loaded, however using the point toward function during docking does not work well. 
it will be issues, you can see this using mechjeb docking autopilot on the primary craft and you see that you uses far more monoprop, and the autopilot is very smooth in docking.
I sometimes uses this but then only to rotate huge ships, the final docking is done with target on SAS only. 

the issue is that the target will rotate around center of mass and not the docking port so if you want to dock at the front of an huge rocket the docking port will move around a lot.

Also a radially locked satellite or space station sounds nice.
