Introduces new "randomly pick random seed" parameter. However, just for the
record: having the same sequence more than once within the same sequence
does neither work for rids. Let's just say that this is a feature, not a
bug.
If you want the same randomization of the same sequence twice, you need to
have two different parent sequences, and use the same seed.
