Carry Forwarded Leaves

The Allocation & Carry forwarding of leaves happen by the Fiscal Year in the system. But the Indian Labor laws expect the leaves to be managed/allocated/carry forwarded based on Calendar year. in ERPNext, I can allocate Leaves by any period - so that’s not a problem. But how do I manage the carry-forwarding process? Is there a place where I can change the logic? If you could point me to the right place, that will be great. Thanks.

As of now, you might have to reallocate them manually.
