I have two views that I would like to combine into one.

The first view shows all items of X where company ID = Y. This is to give preferential sort to the client first, and then everyone else.

So I created a second view, all items of X, where company ID != Y.

I created it as an Attachment to attach to the first view, but I don't think I got the intended result.

How can I combine these views so the first view results are listed first, and then the second view is too, using the same pager, filters, and arguments?

Is there any way of achieving this without programming it?
