how to do one-time reinstatement cost and interface future invoices to current AP period?

1) how to add a one-time reinstatement cost to the Lease, (expense incurred by the lesser on renovations done on the leased building), at the end of the leased asset?

2) is it possible to interface future-period AP invoices from the Lease to the current AP open period? for e.g. when Lessee wants to pay next month's lease rental in current open AP period?
