Sorry, I'm not sure if i understand you fully. English isn't too great.

Have you started a game and you now want to go back to the editor and add players into your team so that they will be there in your saved game?

If that's what you mean, then no. You can't do that.

The in-game FM 2007 editor allows you to edit the database before you start a game

If you have already started your game and want to edit something you will need to use the FMM save game editor- there is a link for it in this forum
