Any way to scan all topics in a specific group for new links?

[MNBlockHead]

I know that you can scan all topics in the navigation panel for new links, but I don't know of any way to filter to just one group. For example, I would like to rescan all topics in the Places/Adventure Area group.

But there appears to be no way to filter by group.

I would be nice if I could click on the tools button on a group's horizontal tab and select scan all topics in group for new links, or "show only topics in this group".

Any other ideas short of spending a lot of time creating and applying custom tags or adding topics to a view, both of which would take a lot of time for the same reason -- no easy way to filter on a specific tab (that I know of).
