Running Design Alternatives

I just got an email from Bentley offering to let me try STAAD.Pro for free. This is funny because I've had STAAD.Pro forever. Anyway, one of the bullet points is "Run many design alternatives in parallel and display comparisons faster than ever before!" Does anyone know specifically what they are talking about? This would be nice because I'm often trying alternatives to how something is framed so I will save the .std file with a different name, say "Option 2.std", then change the framing, then see if it was actually an improvement. If it was I'll delete the original file then name Option2 whatever the original file name was. If it doesn't offer an improvement, I simply delete the Option2 and go back to my original file.

Have I been doing this the hard way?
