add the option to modify someone's reservation at point of checkout.
When a staff user reserves a cart those items are bundled together and no modifications can be made. In my situation when someone comes to pick up equipment it is possible that the person before hasn't returned something they need and I need to make modifications. Right now I have to cancel their entire reservation, make a new cart and check it out under their name. It would be nice to be able to delete items individually out of a cart reservation.
This was patched a while ago. Before proceeding to the checkout, you can use the Edit option (last column on reservations list) and remove items as per your needs.
