Snippets Column Config - Roll with the dice, or ignore the dice

Hi.

On the Snippets page, currently, every roll of the dice (potentially) chooses a different snippet in every column.

Sometimes that is desired, but sometimes not.

One common case would be wanting all the columns to follow the dice except the harmony column.  The point in this case being that the user only wants a harmony change when explicitly asked for.

Of course, the concept is general, and may apply to columns other than Harmony (Group 4 in the picture above).  

So, I suggest that columns be given a settable property:   Follow the Dice  Yes/No

P.S.  How can I change the name of 'Group 4' above to 'Harmony'?

Thanks!
