This is a tricky one (for me

).
I have two content areas - a main content area and a sidebar. Every sidebar of every page has a newsfeed created by a ditto call.
On the main pages for the news (/news.html), that means there is a ditto call for the newsfeed in the sidebar as usual, *and* a larger newsfeed in the main content area. What I would like to do is to suppress the sidebar newsfeed on this one page.
Of course I have searched the ditto documentation, but it is by and large over my head at the moment. If anyone knows if this is possible, or could point me to the relevant area in the documentation, I would appreciate it.
Thanks.
