[Feature Request]Set random seed to each env

[AndssY]

Recently, it appears that seeds can only be sequentially assigned to environments, i.e. the seed for the i-th environment is set as i+seed.
Is there any way to assign a completely random seed to each environment? Like input a list of random seed. Is there any solution？

Yes, but that requires changing the c++ code. I'll try to revive master ci this week and together implement this feature.
