X1 Novice - Saving a "Scene" or a "Mix" ??

Hello,
 
My previous DAW was a Roland VS2480.  There is a feature called "scene", which is common with many older hardware DAW machines.  The description "scene" was used by Roland.
------
The "scene":
You can save / load a scene.  A scene saves all current information necessary to recreate the current status including fader position, send levels, EQ & Pan settings, mutes & solos, locators, automations, all routings and all FX parameters.  The VS2480 had 10 pages of 10 scene locations, 100 total.  Each stored scene can be named.
 
Loading a "scene" returned everything to the state as it was saved.  This allowed me to save work progress as "scenes".  It also allowed me to save multiple "mixes", each recallable by a single click.  The "scene" feature is one I used all the time. 
------
 
Now on the X1, I thought "Screen Set" was the same thing.  Its not.  I know now that it only has to do with the "display status".  I did rome reading on the "snap shot" feature, only to find out it only deals with "Automation".  The word "scene" does not appear in the manual index.
 
I also remember reading about "saving versions" of a project that can be loaded.  If I remember correctly, they are not permanent.  I think I have mine set to 6 versions.  That means every time I save, version 6 gets erased.
 
Being able to recall a "state / status" of a software is an extremely handy feature.  Yet, X1 seems to be lacking this feature.
 
Is there a module hidden somewhere that controls this feature?
 
Is it possible that the only way to save everything is to CREATE A NEW PROJECT with "SAVE AS"??  IF SO, is there a way, other than making the file "read only", to "lock" the file so modification can't be accidentally be made?
 
I'm so used to clicking "Mix 1" and listen to it.  Click "Mix 2" and listen again.  How do you do it?
 
Any help / suggestions are greatly appreciated.
 
Thanks
Ed

Using 'Save As' is a good way to keep different mixes or versions of the same song.

I'm not sure there is another way to do this in Sonar.

A project directory can hold multiple cwp files all pointing to the same audio data.

Submit this feature request via Cake's tech support page. This feature will probably be more useful than Screen Sets.

Cramming too much in one project file may not be a good idea. Keeping multiple project files can be a godsend when a project file gets corrupted.
