I'm using Hudson with the option of keeping the latest 5 builds artifacts, as I don't want to waste too
space on the disk. But now that I've added the Cobertura report I'd like to keep track of the progress of the
coverage, so I'm going to manually mark a build as "keep forever" every 30 days. In this time I'll have a
permanent history of the coverage conveniently sampled.

It would be nice to have such an option in the UI - i.e. "Automatically mark as keep forever" every N builds
or days.
