Can you change the Liability Reclassification Method after lease module has gone live

Summary:

When Lease Accounting went live, Liability Reclassification Method was set to Short Term Present Values. It has been a few months since we've been using the module. If we want to change the Liability Reclassification Method to Amortized Liability Balance method now, would I be able to do that?

If you are allow to change it, would the system recalculate the existing leases under the new method or just the new leases created after the change?

If you are not allow to change it in the UI, would Oracle Support be able to change it?
