This was added in 20q4, but because of several issues in the release (noted in this [post](https://forum.depmap.org/t/important-update-issues-with-depmap-20q4-data/344)), we reverted the data. The reversion is similar to 20q3 and does not have this flag. We have added this back for 21q1 which you will see in the upcoming release.
