exclude info and trends columns from NK page

Please let me know how to exclude "info" and "trends" columns from the
NK overview page.

I'm using Hobbit Monitor 4.1.2 and my bb-hosts is as follows.
192.168.1.100	internal.domain.com	# http://internal.domain.com NK:http

When http tests fails, this hostname surely appears on the NK page, but
it is with "info" and "trends" colomns even though I specify only http
with NK option in bb-hosts.
