A question about views 2 (more link)

I successfully created a view that generates a block in my group homepage with the latest 4 posts in it.
The block display has the filter "Og:Posts in current group" to show only posts in the current group.

I added a "more link" which uses the page display to render all the posts. The problem is that the page doesn't belong to the group so i get no results even if i check the og filter.
is it possible to preserve the context of the page display?

what I want is that the "more" link lead to a list of post from the group i came from.
Don't know if it's possibile though....
