possible to add pause feature to dist-upgrade?

>It would be helpful, I believe, if there were a pause button on the distribution upgrade window of "update-manager". This would help for people who may

>the consequences of having speeds of about 40k all the way down to 0k per second for an extended period of time.

>I can, of course, cancel the upgrade and restart it, and it will start where it left off... But it does require me to redownload some upgrade files and takes
