Ideas for RoomKeyPMS

Previous PMS systems I have used have the capability to route by date or individual nights. If a guest were part of a group and coming in early or staying late, on their own CC, there should be the ability to split the payment between the group (routing to City Ledger) and the individual guest. I have a group where there is a two night stay, and the guest is on their own for one night and the group is picking up the other night, and I have no way of routing by date or a single one night charge to the City Ledger, until a manual transfer is done at check-out. Which is great if one of the managers is here, but if a front desk employee doesn't know how to do that, you can't check the room out properly.
