Not adding items to created views in View Manager

Hello All,

I am working on a concept which has various possibilities, so I thought I would use view manager to set up to display each one.

All the concepts have around 30 parts, and 90% of the parts are all the same and in the same position. So I want create each view from the Master Rep using Include all,

Then exclude parts I don't want.

But if I then have a new variation for which I add extra parts these get added to the Reps I have already set up. How can I set it so any new parts don't get added to Reps I have created?

It is far too much clicking to set each rep to Exclude everything, then go in and put the 90% of common parts in.

(On that note is there an easier way to Include or exclude groups of items? Seem odd I can't use Ctrl or Shift to highlight multiple items I want to exclude or include.)

Thanks
