Lease asset - Unable to process the purchase option

Summary:

Currently, in the tax book, it is not possible to exercise the purchase option on a lease asset once its term has ended.

According to the standard process, the purchase option must be exercised before the end of the lease term (i.e. during the last period).

If this process is not done in time (before the last period), the lease asset cannot be modified after its term

However, we need to exercise the purchase option due to business requirements. The asset could be purchased at the end of the lease or not.

Is it possible to do this after the lease term has ended?
