I don't know if it's possible to do something, but Exophase can't detect achievements in games that are offered for sale as packages on GOG.
A striking example is Blackwell Bundle, which contains 4 games, all with Galaxy achievements, but none of them is present in the Exophase database. But there are many other cases.
