[NTG-context] Disable balancing of page bottoms

Dear list! Context (Mk IV) balances the bottoms of doublesided pages, even if I use \raggedbottom. How can I disable this? I'm thinking of something like "balance=no" for columns, only for pages. My problem is that I have a one-page float (rotated table) with the size of the textheight. The opposite page is not completely filled with text, which makes context crop the height of the page with the float, too, resulting in a shift of the float into the upper margin. That's why I want to disable balancing. Kind regards, Joshua Krämer
