Suggestion regarding archived games page

It would be great if you could update the personal game archive feature with a very basic filter function. Every month or so I merge all the new live chess games I've played with a database of my games. Because I often do some light annotations on the games, its important that I can merge the new ones with the old ones. The problem I'm having is that I want to request a relatively large amount of games that spans through multiple site pages. When I try selecting the games I want I find that my previous selections are no longer check marked when I navigate between pages. Each time I end up requesting the pgn file of all my games, which is not a big problem, but it would be nice if I didn't have to sort this out on chessbase and have to wait for the file of all my games to be generated. Basically, what I'd like is for there to be some way of requesting pgns of games from date x to date y.

Thanks!
