Multiple query loops on one page: Only show unique?

This might be a feature request, since I don’t know if this can be done with Cwicly as it is.

Imagine you have a page with multiple query loops on it. One query shows posts in the category “News,” and the other shows posts in the category “Travel” If a post is in both “News” and “Travel” categories, it will be shown in both query loops.

Is there a way to exclude posts that are already part of a query loop above it? The way I imagine it would be done would be updating an array of posts with each query loop, then set the query loops to exclude posts in that array.
