Minus front on 3 layers

Hi All,

I see a form of this question has been asked many times, but not in the form that answers my question.

Perhaps someone can assist please -

If I want to minus front on more than 2 layers how would I do this.

As you can see below: If I want to push the blue bar though the white bar, I would use the normal minus front, and result in the second image:

But what if I wanted to go through the bottom gradient layer as well in one operation? What is an easy way to do this as I often need to use this function.

Thanks,

Darren
