No. Once the milk or formula has been heated, it should not be heated again once it has been out long enough to cool. Previously heated milk or formula should also never be stored in the refrigerator and reheated later.

EDIT TO ADD: The reason for this is that once the baby's mouth comes in contact with the milk, even just through sucking it through the nipple of the bottle, new bacteria is introduced to the milk. The milk will not get cold enough to kill or limit the bacteria growth in the fridge, and it will not get warm enough to kill it. The bacteria naturally occurs in all babies' mouths. Our immune systems regulate the growth of the bacteria in our bodies--allowing what we need, killing off excess. There is nothing in the milk to keep the bacteria from growing out of hand, then when the baby drinks it, it will be too much for the immune system to handle at once and make the baby sick.
