Save Copy As should be more automatic

From the change log:
 
""Miscellaneous File | Save Copy As… command This allows you to save a copy of the file as a new name but continue working on the sameproject file name. This is different from Save As which switches your current working project to a new file name.
""
 
So, like this really has me confused. (Not unusual. I am only a man.)
 
I find no difference between the '15 dialogs displayed and what I have FOREVER needed to use SAVE AS to properly save a project, except one is labeled "Save Copy As."
 
What am I missing?
 
What I expected from SAVE COPY AS is to sorta add a,b,c,....
Examples:
   GreatProject 0215 a.cwp
   GreatProject 0215 b.cwp
   GreatProject 0215 c.cwp
And so on.
 
Or, add the date and time just before the ".cwp."
 
The type of file save should be user defined.
 
This also should be the default for the AUTO-SAVE settings.
 
Get through the alphabet and the file name would be incremented to 2,3,3,4...
 
Would be good to do it like I do: Song Name   MonthYear    type of increment: a,b,c,d,...
 
   See examples above.
 
I am sure I do appreciate only having to click once.
