Accessing RDS File for Release 4.0

Hey ABCD Repronim Community,

Professor Wes Thompson highlighted in Week 2 lecture the advantages of using an RDS file for analysis as compared to separately downloading individual measures. Is there an RDS file available for release 4.0, similar to how one is available for release 3.0 at this nda link. I could locate the data release 4.0 at this nda link, but the link has the individual files instead of the rds file.
