Xbox 360: Please add a feature to edit played games list

To Microsoft:

We the gamers of the Xbox 360 have or heard a lot of complaints about the Played Games list. We need a way to delete games from this list to get them off completely. Every game that appears on this has been a game that has been under our systems at one point or another under our profiles even if it was by accident.

The reason we want to be able to delete items from it is for many reasons. I have heard many stories from people and reading online that fill the same way as me about it. Some of the top reasons are listed below:
1) Older arcade demos appear. If we cant get achievements from them why should they show on the list? I have heard newer ones dont and that is a step in the right direction. Some of us dont buy a lot of arcade games because we want to try them first but dont want them being added to the list of the played games so we wont try the demos either.
2) Roommates, family, friends etc. Almost all of us has had a game loaded/downloaded and played for one of these reasons. A lot have never been played by us. Yet there they are on the list.
3) Rentals or borrows. A lot of us rent or borrow games to try them. We never play or dont like them and never mess with them again after returning them.
4) Trade-ins or sell games. Some of us buy games because of many reasons. We dislike them so we trade-in at places or sell to other people. We dont own them anymore; we shouldnt have them on the list.
5) Some of us older gamers want to play games designed for younger without people knowing that we played/play them. A few of us have turned down what could be great games because of it being designed for children or another target group. The only way around that is to start up a new account and another e-mail to have some privacy from friends or family that might tease us about the games we play.

You do many updates on the Xbox 360 and even a lot of Xbox 360 Game updates. Can you please make one to let us delete games off of our played games list? Even if it means any achievements from that game that is unlocked being deleted.
