I wonder ow to construct an Survivorship Bias free asset lists?

If you mean with "Survivorship Bias" the survivors of a stock index, add removed stocks and their history for constructing a bias free list.

if only add removed stocks to asset list file seems not enough. Because at first, it was not in the index then it came in the index, and then it is removed from the index. In the script, I need know when it is in the index and when it is not. Is that possible?
