change intrational debut

Hello gus, i was thinking and wondering what you thnk anout si adding abit to the editor which you can change someones international debut date so if you want to make a database for the year lets say 1999/2000 we can edit his international debut to make it more real rather than have someone like beckham on 100 plus caps at the age of 26, do you think this is a good idea? I know you can change the amount of caps he has to suit it but it would be nice to change his debut date aswell so lets say someone like Rooney doesnt have 50 caps by the age of 16

You can do this with fmrte I think.
