[Plugin: Robots Meta] [content="noarchive"] Per page setting please

Hi, I have had a few pages already indexed by Google, and thanks to this plug-in, that should not happen again, BUT, for the pages already indexed, I have found that I should add content=”noarchive” to the Meta and Google will removed these already indexed pages from the cache/archive. I can see where this is possible to turn this on in the plug-in, but this only seems to effect my main page at the moment, can we have this added so that we can add on a per page/post basis? Just like how you can do it now with nofollow/noindex options.

Cheers, Keep up the good work.
