Mass creation and Scheduling of Pick Wave Release Rules

We need to create and schedule multiple pick wave release rules for SIT implementation milestones, approx. count is around 2000 pick wave release rules.

Let us know how to handle this request. I don't see any solution like FBDI template for mass creation of pick wave release rules or mass update, mass scheduling of pick wave release rules in oracle fusion inventory.

Let me know what the best possible solution is to create multiple release rules and how to schedule them as this may pose a performance issue.

Thanks
