I have some chapter in epub. One chapter in one file.
<itemref idref='text_0' />
<itemref idref='text_1' />...
Book NOT fixed layout.
Book reading in spread mode.

In Apple iBooks - all ok.
But google play books, ADE - start chapter in left part of spread.
I see some logic in this behavior, but i want fix it. How disable blank pages between chapters?
May be we have some like <itemref idref='text_0' properties="page-spread-any"/>

PS. I know about variant "all chapters in one file and use page-break-*".
