my quest dont was for new save game, i mean if i can save for char name, for example i make char Pippo and i can save only for Pippo and if i get boring to play with Pippo, for example, i can load savegame of other char that of course have another name, i think there is a way but is not automatic in the game this is sure and is incredible why bethesda don't thinked about..
You can give your Savegames individual names ingame by opening the console and then type "save Pippo1". After that you can play or create another char, Mario, and save that as Mario1.
I do that with my chars too. In case of Pippo and Mario you can make savegames like Pippo1, Pippo2 and Pippo3 (the same with Mario). So you have 3 savegames for each character.
But don′t forget that autosave and quicksave are shared.
