You'll have the option to pick which save you want to import to Mass Effect 3. Unlike the original Mass Effect where it would create a save at the end of the game for importing, Mass Effect 2 allows you to choose a save. So simply save the game at a point you wish to import to Mass Effect 3 and remember the save number.
