The should have the basic charter save files but you should be able to switch between your charter choices. I think most of us are doing at least 3 types of charter bases I want to play a warrior type and maybe start a mage type or thief. just add the ability to easier load show a charter type and level in the load screen. If im playing a orc warrior and get to level 5 then decied to try my hand at a highelf mage I dont think I shouldn't have to worry about saving over other play throughs. Organize charters by name or how ever just make different charter save locations. Its not like Oblivion where you can save before you exit the sewers and change charter type
