When you operate throw Generic Control Surface or Remote Control, what you assign as particular MIDI tracks inputs is not relevant. Automation writing does not influence CC writing for MIDI track.
But I have hard time to understand what you are doing in general.

I am able to set the MIDI tracks Auto Write button to a remote. It engages but doesn't engage the global or each Write within the track such as a volume envelope. The envelope can and is assigned to any CC. When the button is pressed in Sonar itself this occurs.

I am using 48 channels. So I have 48 midi tracks set up in my template each with an envelope assigned to a CC.
Everything works but arming the envelope. In Sonar, when you press the arm button on a Midi track all the envelopes on that track are armed. But it is not doing this by remote control.

That bug I can confirm...
 
For up to 32 tracks I can propose the following solution: insert Cakewalk Generic Surface, configure it for 32 channels (unfortunately that seems to be the maximum). Set Parameter 1 to "Write Enable" and assign some notes to it.
Unlike "Remote control...", that method arm automation correctly.
 
If you need 48 channels, I can make a preset for AZ Controller for you. Just say which note range / channel you prefer for that.

That's what's fun. I only need 32 tracks but it is 2 units. One only takes 16. So just use the control surface? Don't set the automation to a note on at all?

I can use two Surfaces. One for 32 channels and another for 16. Works great. Do the presets store inside the dll? Can I copy the dll to another DAW?

After you save preset using controls in the top left of Generic Surface interface, you can export/import it using Cakewalk Plug-in Manager from Utilities menu. But note! If you have 2 instances of surface, do not open interfaces for them simultaneously! Also both will show the same preset name, which is not real. Just be careful with preset saving and manually type required name every time you want to save it.

I have 3 instances and it works great.  You simply start your base track accordingly. The utilities manager works great. Thanks!
 
I have found that there is no global read auto now.  The read is the same thing.  Won't engage/ disengage via remote.  But there is no control in the Generic Surface.  A mute of the MIDI track does,  but I would have to toggle a MIDI channel as my Mutes are already in use as they were intended.  To send a Mute to the MIDI track on an unused MIDI channel would allow for the automation to mute,  but not send the "Mute" command to my hardware.  Might try it.
